The effectiveness of using mesodiencephalic modulation in combination with ozone therapy in patients with peri-implantitis according to long-term results of the study

BACKGROUND: Evaluation of the clinical effectiveness of the use of various treatment regimens for peri-implantitis should take into account not only the immediate results achieved during treatment, but also the manifestations of the disease in the long-term period. AIM: Assessment of the effectiveness of the integrated use of mesodiencephalic modulation (MDM therapy) and ozone therapy in patients with dental peri-implantitis based on long-term results of the study. MATERIALS AND METHODS: The study was carried out with the participation of 116 patients with peri-implantitis of classes I and II according to S.A. Jovanovic. Using the fixed randomization method, all patients were divided into 4 groups based on the results of generating random numbers obtained using a computer program. Patients of the first group (control group, n=28) received standard dental therapy, including professional oral hygiene and local use of antiseptics. Patients of the second group (comparison group 1; n=29) received a course of ozone therapy in addition to standard dental therapy, for which the periimplant area was irrigated with ozonated saline solution with an ozone concentration of 2.5–5.5 μg/ml for 15 minutes. Patients of the third group (comparison group 2; n=30) received a course of MDM therapy in addition to standard dental therapy. In the fourth group (main group; n=29), patients, along with standard dental therapy, received a course of complex physiotherapy in the form of a combination of ozone and MDM therapy. Long-term results of complex therapy for peri-implantitis were assessed 6 and 12 months after the end of treatment. RESULTS: A comparative assessment of dental indices in the long-term period showed that the addition of SST with a course of physiotherapeutic effects, in general, is accompanied by the preservation of the effect achieved after the end of treatment. At the same time, the best results were noted in the main group with the combined use of ozone and MDM therapy. Changes in the osseointegration index also indicated the preservation of the values achieved after the end of therapy, and in the main group a significant increase in this parameter was observed, which indicated additional activation of osseointegration processes under the influence of the physiotherapeutic complex. CONCLUSION: The results of the performed follow-up study convincingly prove the advantages of the additional use of therapeutic physical factors (MDM therapy, ozone therapy and their combination).

The Role of Keratinized Mucosa in Peri-Implant Tissue Stability after Treatment of Peri-Implantitis. Clinical and Radiographic Outcomes of a Prospective Cohort Study after 3 Years.

This study prospectively evaluated the effect of keratinized mucosa (KM) on the healing of the peri- implant tissues after resective surgical therapy for peri-implantitis. It addressed the question of whether the absence of KM has a negative effect on peri-implant tissue stability after treatment. Patients referred to a private practice for peri-implantitis treatment were surgically treated with resective flap surgery and implantoplasty. They were followed for 3 years and measurements at implant level included presence of plaque, bleeding on probing, probing pocket depth, radiographically visible bone loss and the presence and width of KM before therapy, 3 month post-operatively, 1 year, 2 years, and 3 years after the surgical intervention. All clinical parameters improved and marginal bone levels remained stable 3 years after therapy. The width of the KM decreased significantly after the therapy. Soft tissue recession was frequently observed. The absence of KM does not seem to have a negative effect on healing after therapy for the studied period of 3 years. The authors conclude that resective surgery combined with implantoplasty seems to be a reliable method for arresting the progression of peri-implantitis.

Comparison of the efficacy of Er,Cr:YSGG laser on oral biofilm removal from implant surfaces with various application times for the treatment of peri-implantitis defects: ex vivo study

PurposeThe major struggle in peri-implantitis therapy is the availability of successful decontamination of the infected implant surface. The main hypothesis of this study was the Er,Cr: YSGG laser decontamination efficacy investigation on the infected implant surfaces with various peri-implantitis defects. The primary objective of this study was to decide the efficacy of Er,Cr:YSGG laser as a decontamination tool at various peri-implantitis simulating defects. The secondary objective was to compare the efficacy of the Er,Cr: YSGG laser on oral biofilm removal between two protocols the first protocol (4 cycles at 2.5 min) and the second protocol (5 cycles at 5 min) at various peri-implantitis simulating defects.Materials and methodsA total of 3 subjects whose plaque biofilms formed in-vivo on twenty-four tested implants were divided into four tested groups. Two native implants were tested as controls.The in vitro defect model was computer‐aided designed and printed into a 3D-printed model with various anulations in peri-implant infrabony defects, which were 15,30,60,and 90 degrees.ResultsBoth Er, Cr: YSGG decontamination protocols at 50 mJ (1.5 W/30 Hz), 50% air, and 40% water were effective at reducing the total implant surface area/ biofilm ratio (%), but the second protocol had a markedly greater reduction in the duration of application (5 cycles at 5 min) than did the first protocol (4 cycles at 2.5 min).ConclusionThe Er, Cr: YSGG laser is an effective decontamination device in various peri-implantitis defects. The second protocol(5 cycles at 5 min) with greater application time and circles is more effective than the first one. The defect angulation influence the decontamination capability in peri-implantitis therapy.Clinical relevance (Scientific rationale for study)Clinicians anticipate that the exploration of suitable therapeutic modalities for peri-implantitis therapy is limited by the obvious heterogeneity of the available evidence in the literature and need for a pre-clinical theoretical basis setup. The major challenges associated with peri-implantitis therapy include the successful decontamination of the infected implant surface, the absence of any damage to the treated implant surface with adequate surface roughness, and the biocompatibility of the implant surface, which allows osteoblastic cells to grow on the treated surface and is the key for successful re-osseointegration. Therefore, these are the expected empirical triads that need to be respected for successful peri-implantitis therapy. Failure of one of the triads represents a peri-implantitis therapeutic failure. The Er, Cr: YSGG laser is regarded as one of the expected devices for achieving the required triad.Trial registration"Efficacy of Er,Cr YSGG Laser in Treatment of Peri-implantitis".

Peri-Implantitis.

Peri-implantitis can affect the longevity of successfully integrated implants. Implant success is dependent on reducing the peri-implantitis risk or successfully managing peri-implantitis. Further understanding of peri-implantitis can be derived from its prevalence, microbial and diagnostic findings, existing therapies, and the effects of systemic health issues and medication. Based on published information: (1) peri-implantitis is higher in patients who have periodontitis or smoke as well as in implants with 5 years of function; (2) peri-implantitis microflora is different from periodontitis; (3) peri-implantitis risk is increased in patients with cardiovascular diseases and uncontrolled diabetes; (4) most reported peri-implantitis therapies may result in resolution, but the best peri-implantitis treatment is still to be determined; (5) more frequent peri-implant maintenance may reduce risk for peri-implantitis.

Evaluation of the effect of adjunctive diode laser application on peri-implant crevicular fluid biomarker levels: a randomized controlled trial

ObjectivesTo assess both the clinical and immunological effectiveness of diode laser therapy when used as an adjunct to non-surgical mechanical therapy in managing peri-implantitis.Materials and methodsA cohort of 27 participants, comprising 21 females and 6 males, agreed to take part in this investigation. 37 dental implants with peri-implantitis diagnosis were randomly allocated to either the laser group (n = 19) or the control group (n = 18). Evaluation of peri-implant clinical parameters and collection peri-implant crevicular fluid (PICF) samples occurred at baseline, as well as at 3 and 6-month follow-up intervals. The level of various biomarkers (TWEAK, IL-1β, sclerostin, IL-17, RANKL, OPG and IL-10) within the PICF were quantified using enzyme-linked immunosorbent assay.ResultsSignificant time-dependent decreases in clinical and biochemical parameters were detected in both groups compared to the baseline. There were marked differences between the groups in terms of periodontal parameters, except probing depth, and IL-1β, IL-17, sclerostin levels in PICF at 3rd month follow-up. However, no statistically significant difference was detected at 6th month.ConclusionsDiode laser seems to be a reliable tool as an adjunct for supporting the nonsurgical mechanical treatment during the early stages of peri-implantitis. Furthermore, the findings suggest that IL-17, sclerostin and IL-1β may serve as promising biomarkers for assessing efficacy of peri-implantitis treatment.Clinical relevanceBased on these outcomes, clinicians may consider the application of adjunctive use of diode laser to non-surgical peri-implantitis treatment to achieve better clinical and immunological improvements than nonsurgical peri-implantitis therapy alone in just early healing period. However, it should be noted that there was no difference between the two methods in the long term.

Periodontal plastic surgery and regenerative periodontal surgery in a forty-seven-year-old patient with cleft lip and palate

Cleft lip and palate represent one of the most prevalent congenital malformations in humans, with an estimated prevalence of 0.45 per 1,000 individuals. During childhood and adolescence, affected patients undergo lengthy and complicated interdisciplinary treatment including treatment from specialists in pediatric medicine, oral and maxillofacial surgery, orthodontics, and otorhinolaryngology. The patient exhibited scarred adhesions with localized mucogingival deformities of the premaxilla (region 12 − 11), bilateral cleft lip and palate, and a complex underlying one-wall intrabony osseous defect on tooth 11, in addition to hard- and soft-tissue deficiencies at the dental implant in region 12. Following the administration of localized anti-infective periodontal therapy, regenerative periodontal surgery, regenerative surgical therapy of periimplantitis, and periodontal plastic surgery were performed. This resulted in a long-term, stable improvement in the clinical situation. Regenerative periodontal therapy and periodontal plastic surgery in patients with palato-alveolar cleft present a significant challenge due to the poor condition of the mucosa and gingiva adjacent to the defect and the insufficient bone dimensions. For this reason, it seems beneficial to include the periodontist in the interdisciplinary treatment team of a patient with cleft lip and palate from the outset. It is recommended that the patient be provided with dental prophylaxis measures and receive individualized oral hygiene instructions in addition to the main maxillofacial and orthodontic treatment. This approach would facilitate the identification of mucogingival issues at an early stage and the implementation of appropriate treatment.

Bactericidal Effect of Different Photochemical-Based Therapy Options on Implant Surfaces-An In Vitro Study.

Objectives: Photochemical systems are frequently recommended as an adjuvant treatment option in peri-implantitis therapy. The aim of the present study was to evaluate the efficacy of these treatment options, as well as a novel curcumin-based option, in a biofilm model on implants. Methods: Eighty dental implants were inoculated with an artificial biofilm of periodontal pathogens and placed in peri-implant pocket models. The following groups were analyzed: I, photodynamic therapy (PDT); II, PDT dye; III, curcumin/DMSO + laser; IV, curcumin/DMSO only; V, dimethyl sulfoxide (DMSO) only; VI, photothermal therapy (PTT); VII, PTT dye; VIII, control. After treatment, remaining bacterial loads were assessed microbiologically using quantitative real-time polymerase chain reaction analysis. Results: The PDT, PTT, and DMSO treatment methods were associated with statistically significant (p < 0.05) improvements in germ reduction in comparison with the other methods and the untreated control group. The mean percentage reductions were as follows: I (PDT) 93.9%, II (PDT dye) 62.9%, III (curcumin/DMSO + laser) 74.8%, IV (curcumin/DMSO only) 67.9%, V (DMSO) 89.4%, VI (PTT) 86.8%, and VII (PTT dye) 66.3%. Conclusions: The commercially available PDT and PTT adjuvant treatment systems were associated with the largest statistically significant reduction in periopathogenic bacteria on implant surfaces. However, activation with laser light at a suitable wavelength is necessary to achieve the bactericidal effects. The use of curcumin as a photosensitizer for 445 nm laser irradiation did not lead to any improvement in antibacterial efficacy in comparison with rinsing with DMSO solution alone.

Periodontal conditions of teeth adjacent to dental implants with or without peri-implantitis after non-surgical therapy in patients treated for periodontitis: A retrospective study.

To retrospectively assess the periodontal conditions of teeth adjacent to and contralateral to implants presenting with or without peri-implantitis, following non-surgical periodontal and peri-implant mechanical therapy. One hundred and one patients with existing dental implants and chronic periodontitis, who underwent non-surgical periodontal and peri-implant mechanical therapy, were included. The periodontal clinical probing depth (PPD), gingival recession (GR), and bleeding on probing (BOP) were recorded at six sites around the adjacent (Adj-) teeth and the contralateral (CL-) teeth relative to the implant. The potential factors influencing the periodontal conditions of 316 teeth were analyzed by multivariate linear regression models with generalized estimating equation methods and α = .05. The PPD of Adj-teeth was significantly different from that of CL-teeth before and after non-surgical therapy when the implant was diagnosed with peri-implantitis (PI) (p < .05). The PPD of teeth was shown to be affected by neighboring implants diagnosed with peri-implantitis (β = .825 mm, p < .001), teeth adjacent to implants (β = .245 mm, p = .004), a molar tooth type (β = .435 mm, p = .019), and non-surgical therapy (β = -.522 mm, p < .001). Relatively compromised periodontal conditions at Adj-teeth after non-surgical PI therapy were detected. Therefore, clinicians should be aware that non-surgical therapy may be less successful at teeth adjacent to implants with PI.

Training in the use of the water jet and cold atmospheric plasma jet for the decontamination of dental implants

ObjectivesClinical trials testing new devices require prior training on dummies to minimize the "learning curve" for patients. Dentists were trained using a novel water jet device for mechanical cleaning of dental implants and with a novel cold plasma device for surface functionalisation during a simulated open flap peri-implantitis therapy. The hypothesis was that there would be a learning curve for both devices.Materials and methods11 dentists instrumented 44 implants in a dummy-fixed jaw model. The effect of the water jet treatment was assessed as stain removal and the effect of cold plasma treatment as surface wettability. Both results were analysed using photographs. To improve treatment skills, each dentist treated four implants and checked the results immediately after the treatment as feedback.ResultsWater jet treatment significantly improved from the first to the second implant from 62.7% to 75.3% stain removal, with no further improvement up to the fourth implant. The wettability with cold plasma application reached immediately a high level at the first implant and was unchanged to the 4th implant (mean scores 2.7 out of 3).ConclusionA moderate learning curve was found for handling of the water jet but none for handling of the cold plasma.Clinical relevanceScientific rational for study: Two new devices were developed for peri-implantitis treatment (Dental water jet, cold plasma). Dentists were trained in the use of these devices prior to the trial to minimize learning effects.Principal findings: Experienced dentists learn the handling of the water jet very rapidly and for cold plasma they do not need much training.Practical implications: A clinical study is in process. When the planned clinical study will be finished, we will find out, if this dummy head exercise really minimised the learning curve for these devices.

Do systemic amoxicillin and metronidazole during the non-surgical peri-implantitis treatment phase prevent the need for future surgical treatment? A retrospective long-term cohort study.

The aim of this retrospective long-term follow-up of a 3-month RCT was to assess whether non-surgical peri-implantitis treatment with adjunctive systemic antibiotics influenced the need for additional surgical treatment. Patients enrolled in an aftercare programme following non-surgical peri-implantitis treatment, with or without systemic amoxicillin and metronidazole, were analysed. Data had previously been collected pre-treatment (T0) and 3 months after treatment (T1) and were additionally collected during subsequent aftercare visits, until the final assessment (T2). Primary outcome was the need for additional surgical peri-implantitis therapy during the aftercare programme, analysed via Kaplan-Meier analysis and Cox regression. Secondary outcomes involved clinical parameters, assessed using parametric and non-parametric tests. Forty-five patients (22 AB- group, 23 AB+ group) were included. The mean follow-up time between T1 and T2 was 35.9 months (SD = 21.0). 73.9% of the AB+ group and 50.0% of the AB- group did not receive additional surgical therapy (log-rank test, p = .110). The adjusted Cox regression model did not provide a significant result for antibiotics (β = .441, 95% CI = 0.159-1.220, p = .115). Univariable regression analysis highlighted the influence of baseline peri-implant pocket depth on the need for surgical treatment (β = 1.446, 95% CI = 1.035-2.020, p = .031). Systemic amoxicillin and metronidazole administered during non-surgical peri-implantitis treatment do not seem to prevent the need for additional surgical therapy in the long term, during a structured aftercare programme.

Electrolytic Surface Decontamination in the Reconstructive Therapy of Peri-Implantitis: Single-Center Outcomes of a Randomized Controlled Trial.

Surface decontamination in the reconstructive therapy of peri-implantitis is of paramount importance to achieve favorable outcomes. The objective of this single-center study derived from a large multicenter clinical trial was to compare the electrolytic method (EM) used as an adjunct to mechanical decontamination, to hydrogen peroxide (HP) also used as an adjunct to mechanical decontamination, in the reconstructive therapy of peri-implantitis. At 12-month (T2) follow-up, 19 patients (Nimplants= 23) completed the study. None of the tested modalities demonstrated superiority in terms of the assessed clinical parameters. Only mucosal recession showed higher stability in the EM group. Alike, radiographic marginal bone level gain and defect angle changes at T2 did not differ between the evaluated strategies. Notably, disease resolution was ∼16% higher in the EM; however, differences did not reach statistical significance. Additionally, it was demonstrated that pocket depth and intra-bony component depth at baseline were predictors of disease resolution. In conclusion, the EM combined with mechanical instrumentation results in a safe and effective surface decontamination modality in the reconstructive therapy of peri-implantitis. This strategy resulted in ∼91% disease resolution rate.

Decision Tree for Reconstructive Treatment of Peri-implantitis Defects.

Peri-implantitis, a common complication among patients receiving implant-supported restorative therapy, often requires surgical intervention for effective treatment. Understanding the specific configuration of peri-implant bony defect and adjacent bone peaks is crucial for tailoring treatment strategies and improving outcomes. A decision tree for reconstructive peri-implantitis therapy has been developed based on the new classification of defect configurations (Class I to V), guiding clinicians in selecting treatment options, including biomaterials, techniques, and healing approaches. Furthermore, clinicians are encouraged to consider various factors such as local predisposing factors (such as soft tissue characteristics, prosthetic design, and implant position in three-dimensional perspective), clinical factors (surgeon skill and experience), and patient-related factors (such as local and systemic health, preferences, and cost) when evaluating reconstructive therapy options.

Change in parameters of the microcirculatory tissue system of the peri implant zone in patients with peri implantitis during complex use of mesodiencephalic modulation and ozone therapy

Abstract. Purpose of the study: The article examines the role of microcirculation disorders in the pathogenesis of peri-implantitis in patients after dental implantation. Materials and methods. It is shown that the development of peri-implantitis is characterized by significant changes in the parameters of microhemodynamics and oxygen exchange in the tissue involved in the inflammatory process. The state of oxygen and energy deficiency prompts the progression of inflammatory changes with the formation of signs of tissue destruction around dental implants. The application of a standard scheme of peri-implantitis therapy is accompanied by a correction of the microcirculatory tissue system indicators. The supplementation of standard treatment with course use of medical physical factors promotes the strengthening of the positive dynamics of microcirculation parameters of the peri-implant zone. The corrective influence of MDM-therapy is connected with the activation of the mechanisms of neuroendocrine regulation of vegetative functions, while the basis of ozone therapy is the polymodality of the factor, including the relaxation of the precapillary blood flow, improvement of the rheological properties of the blood, and the stimulating effect on angiogenesis processes. Results. The complex application of medical physical factors, combining systemotropic and local impacts, different modalities and points of application of their corrective activity, contributes to the manifestation of functional potentiation with a maximal corrective effect.

Numerical study on the three-dimensional temperature distribution according to laser conditions in photothermal therapy of peri-implantitis

PurposeDental implants have been successfully implemented as a treatment for tooth loss. However, peri-implantitis, an inflammatory reaction owing to microbial deposition around the implant, can lead to implant failure. So, it is necessary to treat peri-implantitis. Therefore, this numerical study is aimed at investigating conditions for treating peri-implantitis.MethodsPhotothermal therapy, a laser treatment method, utilizes photothermal effect, in which light is converted to heat. This technique has advantage of selectively curing inflamed tissues by increasing their temperature. Accordingly, herein, photothermal effect on peri-implantitis is studied through numerical analysis with using Arrhenius damage integral and Arrhenius thermal damage ratio.ResultsThrough numerical analysis on peri-implantitis treatment, we explored temperature changes under varied laser settings (laser power, radius, irradiation time). We obtained the temperature distribution on interface of artificial tooth root and inflammation and determined whether temperature exceeds or does not exceed 47℃ to know which laser power affects alveolar bone indirectly. We defined the Arrhenius thermal damage ratio as a variable and determined that the maximum laser power that does not exceed 47℃ at the AA’ line is 1.0 W. Additionally, we found that the value of the Arrhenius thermal damage ratio is 0.26 for a laser irradiation time of 100 s and 0.50 for 500 s.ConclusionThe result of this numerical study indicates that the Arrhenius thermal damage ratio can be used as a standard for determining the treatment conditions to help assisted laser treatment for peri-implantitis in each numerical analysis scenario.

Background: Dental peri-implantitis is an inflammation that occurs in the peri-implant soft tissue and is accompanied by bone resorption, decreased osseointegration, and pockets. Graptophyllum pictum L. Griff extract may act as complementary therapy for peri-implantitis. Objectives: To investigate the effectiveness of G. pictum L. Griff extract as a complementary therapy for peri-implantitis. Materials and Methods: A phytochemical test was performed to determine the active compounds using each compound's reagents. Antioxidant assay to examine the antioxidant activity compared with vitamin C. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) tests were used to investigate the antibacterial activity of Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Fusobacterium nucleatum (Fn), and Provotella intermedia (Pi) as peri-implantitis-related bacteria. Molecular docking is an in-silico test to visualize the interaction of G. pictum L. Griff molecules with targeted proteins using several software programs and databases. This study was analyzed by parametric and non-parametric variance analysis and continued with a post-hoc test. Results: G. pictum L. Griff extract contained flavonoids, alkaloids, saponins, tannins, steroids, and terpenoids. The antibacterial effect of G. pictum L. Griff can inhibit the growth of dental peri-implantitis-related bacteria such as Aa, Pg, Pi, and Fn with a minimum 25% extract concentration. In silico, the interaction of ethylcholest and proteins shows possible pharmalogical effects such as anti-inflammatory, antibacterial, and antioxidant activity. Conclusion: G. pictum L. Griff extract possesses good antibacterial, antioxidant, and anti-inflammatory activity that may be effective for dental peri-implantitis complementary therapy as documented in silico and in vitro.

Current Concepts for the Treatment of Peri-implant Disease.

Peri-implant diseases are defined as bacterial plaque-induced inflammatory conditions affecting implant-surrounding tissues and are classified as peri-implant mucositis and peri-implantitis. Peri-implant mucositis is characterized by an inflammatory lesion that resides in the soft tissue compartment, whereas at peri-implantitis sites the lesions also feature progressive loss of implant-supporting bone. Inflammation resolution and disease progression arrestment are the main therapeutic endpoints of the treatment of peri-implant diseases. The present position paper displays the current evidence and clinical recommendations of the European Association for Osseointegration for the treatment of peri-implant diseases. Mechanical biofilm removal along with the reinforcement of patient-administered oral hygiene is considered the standard treatment for managing peri-implant mucositis. It is recommended to assess the outcomes of peri-implant mucositis treatment 2 to 3 months after therapy, and repeated intervention should be considered in the absence of treatment success. Peri-implantitis treatment should follow a stepwise treatment approach, starting with nonsurgical treatment followed by surgical intervention, if that is not sufficient. Surgical peri-implantitis therapies include nonreconstructive, reconstructive, and combined treatment modalities. Implantoplasty may be advocated for the treatment of supracrestal peri-implant defects, whereas reconstructive therapy is indicated at peri-implantitis sites featuring intraosseous defects with a depth ≥ 3 mm. Adjunctive reconstructive measures may be beneficial in enhancing radiographic defect fill and maintaining postoperative soft tissue levels, which may have a great impact in esthetic cases. The adjunctive use of systemic antibiotics during surgical therapy does not seem to improve the clinical outcomes. Regular supportive peri-implant therapy with biofilm removal should be an integral part of the treatment protocol for peri-implant diseases. In the presence of advanced bone loss around implants that do not play a strategic role in masticatory function, implant removal may be considered immediately.

Combined Treatment of Peri-Implantitis in Patients with Type 2 Diabetes Mellitus

Objective: To evaluate the outcome of combined therapy of peri-implantitis in patients with type 2 diabetes mellitus. Methods: Study included 46 patients with type 2 diabetes mellitus diagnosed peri-implantis. 24 implants with early peri-implantitis, 18 implants with moderate peri-implantitis. The diagnostic parameters used for assessing peri-implantitis include clinical indices, Probing Pocket Depth (PPD), Bleeding on Probing (BOP), peri-implant radiography, data at the re-examination were retrospectively compared to baseline data. Patients underwent treatment with HbA1c levels &lt;7.2% or less than 154 mg/Dl. Results: A statistical significant reduction in both PPD and BOP were seen at all-time points as compared with the baseline clinical measurements. Stable clinical measurements PPD and BOP were demonstrated after 1 year the initial treatment, remaining stable during the following three years. The mean BOP in patients before treatment of peri-implantitis was 2.5 ± 0.31, after 6 months treatment month treatment 0.6 ± 0.1. The mean PPD in patients before treatment of peri- implantitis was 5.2 ± 0.24, after 6-month treatment pocket was 3.2 ± 0.1. Conclusion: Conservative treatment with systemic antibiotics, pocket elimination was an effective therapy in peri-implant mucositis and еarly periimplantitis, when peri-implantitis category moderate surgical treatment combined conservative therapy effective method in patients with type 2 diabetes mellitus.

Analysis to evaluate novel separable dental implant stability: An experimental study in rabbits

Background/purposePeri-implantitis is a representative etiology that affects the long-term survival of dental implants. It is known that decontamination of the implant surface is essential for the successful outcome of regenerative therapy for peri-implantitis. In the present study, the stability of a novel separable dental implant (SDI) was evaluated and compared with a conventional non-separable dental implant (NDI) using biomechanical and histomorphometric analyses. Materials and methodsIn this animal study, 40 rabbits were implanted with two SDI fixtures in the left tibia and two NDI fixtures in the right tibia. The rabbits were sacrificed 3 and 6 weeks after implantation, and the implant samples were evaluated using resonance frequency analysis (RFA), micro-computed tomography (CT), removal torque testing, and histomorphometric analysis. ResultsSDI exhibited comparable or better osseointegration and implant stability to NDI. In particular, SDI showed significantly higher implant stability quotient (ISQ) values immediately and 6 weeks after implantation, while removal torque values were significantly higher at both 3 and 6 weeks. In addition, microgaps on the histomorphometric images were not observed and abnormal signs or inflammation did not occur at the connection between the top and bottom parts of the SDI. ConclusionThe novel SDI fixture demonstrated sufficient osseointegration and biomechanical stability compared with NDI in this animal study. In addition, the changeable top part of SDI indicates that it may be effective in easily treating peri-implantitis in clinical practice. Additional future studies on the stability and clinical application after loading to the fixture are necessary.

Predictive factors for the treatment success of peri-implantitis: a protocol for a prospective cohort study

IntroductionPeri-implantitis, a common biological complication of dental implant, has attracted considerable attention due to its increasing prevalence and limited treatment efficacy. Previous studies have reported several risk factors associated with...
