The efficiency of two different synthetic bone graft materials on alveolar ridge preservation after tooth extraction: a split-mouth study

BackgroundAlveolar Bone loss occurs frequently during the first six months after tooth extraction. Various studies have proposed different methods to reduce as much as possible the atrophy of the alveolar ridge after tooth extraction. Filling the socket with biomaterials after extraction can reduce the resorption of the alveolar ridge. We compared the height of the alveolar process at the mesial and distal aspects of the extraction site and the resorption rate was calculated after the application of HA/β-TCP or synthetic co-polymer polyglycolic - polylactic acid PLGA mixed with blood to prevent socket resorption immediately and after tooth extraction.MethodsThe study was conducted on 24 extraction sockets of impacted mandibular third molars bilaterally, vertically, and completely covered, with a thin bony layer. HA/β-TCP was inserted into 12 of the dental sockets immediately after extraction, and the synthetic polymer PLGA was inserted into 12 of the dental sockets. All sockets were covered completely with a full-thickness envelope flap. Follow-up was performed for one year after extraction, using radiographs and stents for the vertical alveolar ridge measurements.ResultsThe mean resorption rate in the HA/β-TCP and PLGA groups was ± 1.23 mm and ± 0.1 mm, respectively. A minimal alveolar bone height reduction of HA/β-TCP was observed after 9 months, the reduction showed a slight decrease to 0.93 mm, while this rate was 0.04 mm after 9 months in the PLGA group. Moreover, the bone height was maintained after three months, indicating a good HA/β-TCP graft performance in preserving alveolar bone (1.04 mm) while this rate was (0.04 mm) for PLGA.ConclusionThe PLGA graft demonstrated adequate safety and efficacy in dental socket preservation following tooth extraction. However, HA/β-TCP causes greater resorption at augmented sites than PLGA, which clinicians should consider during treatment planning.

Comparative analysis of the state of peri-implantation tissues after immediate and delayed implantation

The state of peri-implantation tissues was analyzed according to cone-beam computed tomography. A modified version of the alveolar index (AIm) is proposed to assess changes in the height of the alveolar ridge in the absence of a tooth and the presence of an implant. It was found that delayed implantation is characterized by more favorable long-term results in comparison with direct implantation.

PRESERVATION OF DISTAL BONE DEFECT AFTER SURGICAL EXTRACTION OF IMPACTED THIRD MOLAR

Extracted teeth are still considered a clinical waste and therefore being discarded. It is evident that obtained and prepared autogenous dentin graft (ADG) may be used for guided bone regeneration (GBR) because of similar biochemical characteristics to human bone. Aim: To present a novel procedure in a clinical setting that employs freshly extracted teeth that are processed into a bacteria-free particulate dentin, and then grafted immediately into extraction sites or bone deffects. Monitoring the clinical and radiological parameters in the postextraction defects of the alveolar ridges for a period of 6 months, proving the rapid healing capacity of ADG on the bonе and soft tissue structures in the jaw bones. Methods: Clinical measurements were performed using a questionnaire for monitoring the postoperative clinical manifestation, bone measuring calipers and for measuring the horizontal changes of the alveolar ridge and a graduated probe for measuring vertical dimensional changes, also paraclinical-radiological examinations to follow-up bone density. Results: During the follow period of six months, clinical measurements of post-extraction dimensional changes of the alveolar ridges shows minimal horizontal and vertical bone resorption with preserved alveolar ridge volume, with an accelerated bone regenerative process without special postoperative complications. Conclusion: Dentin particulate grafted immediately after extractions should be considered as the gold standard due to its osteogenetic, osteoinductive and osteoconductive effects on bone tissue regeneration.

Anatomical Factors Affecting the Complexity of Maxillary Sinus Augmentation in Saudi Patients: A Cone Beam Computed Tomography (CBCT) Study.

This study aims to evaluate the anatomical variations of the maxillary sinus and determine the difficulty score of maxillary sinus augmentation (MSA) in Saudi patients seeking dental implant rehabilitation of the posterior maxilla using cone beam computed tomography (CBCT). CBCT records of dental patients seeking treatment at a University Dental Teaching Hospital between 2019 and 2023 were retrospectively analyzed. Measurements were obtained from CBCT images, including membrane thickness, sinus width, buccal bone thickness, presence of maxillary sinus septa, residual alveolar ridge height, angle of the buccolingual sinus wall, and the presence of the alveolar antral artery (AAA). The difficulty score for MSA was determined based on these anatomical factors. A total of 107 maxillary sinuses in 86 subjects were evaluated. The average membrane thickness was 2.23 mm, with males showing significantly higher thickness than females. Sinus septa were found in 54 (50.5%) sinuses, with 18 (17%) of sinuses having interfering septa. Twenty-three (21.5%) sinuses had a residual alveolar ridge height of less than 4 mm. The average angle of the buccolingual sinus wall was 79.39°, indicating a high prevalence of wide-shaped sinuses. The average sinus width was 14.09 mm, with 55 sinuses (51.4%) less than 15 mm. The average buccal bone thickness was 1.07 mm, in29 (27%) sinuses, the thickness was more than 2 mm. AAA was visualized in 60 (56%) of sinuses, with 45 (42%) of sinuses having AAA interfering with the MSA window. In this study, most sinuses were classified as simple or moderate difficulty, with higher membrane thickness, presence of septa, and AAA being the significant risk factors for complications. These findings provide valuable insights for implant surgeons in Saudi patients seeking dental implant rehabilitation of the posterior maxilla, enabling them to anticipate and minimize potential complications during MSA procedures.

Multi-disciplinary management of neonatal acute osteomyelitis of jaws: A report of 2 cases

BackgroundEarly diagnosis of neonatal osteomyelitis is often challenging due to the rarity of such cases and here we are presenting 2 case reports to add to the existing deficient literature. Case 1: A 15-day-old male infant presented with swelling and pus discharge from the anterior region of the mandible. Repeated culture and sensitivity tests revealed a transition from disseminated methicillin-sensitive S. aureus sepsis to methicillin-resistant sepsis. Moreover, there was swelling of the left elbow and right thigh. The Clinical diagnosis made was acute osteomyelitis of mandible associated with disseminated neonatal sepsis (LONS). A multidisciplinary approach was taken for the management by surgical debridement of the lesion alongwith removal of associated primary tooth buds, under specific antibiotic coverage. Case 2: A 20-day old male infant reported with pus discharge from upper lateral region of mouth past 10days. Personal history revealed, abscess in mother's right breast. A soft fluctuant pus pocket with draining sinus was present w.r.t.alveolar region of 54. CT revealed an osteolytic lesion of labial cortex of alveolar ridge in maxillary right first molar region. Pus specimen culture and sensitivity revealed growth of Staphylococcus aureus (MSSA). The clinical diagnosis of acute osteomyelitis of maxillawas made. Initially, antibiotics were prescribed which did not help and finally, surgical debridement accompanied by extraction of 54 tooth bud was done. ConclusionAcute osteomyelitis should always be considered as one of the differentials in infants with clinical signs of sepsis and Multidisciplinary management should be assured for the successful management of such cases.

Computer guided versus freehand dental implant surgery: Randomized controlled clinical trial

ObjectiveThis study compares, in terms of rehabilitation and recovery, freehand implant placement using flapless or mini-flap procedures with the use of 3D implant design software and specialized surgical templates among patients who are partially or completely edentulous. A secondary aim is to propose an algorithm for predicting the accuracy of implant placement. Method.Patients with an alveolar height of at least 7 mm and an alveolar width of at least 4 mm were randomly assigned to two groups. Group I comprised ten patients who received computer-guided dental implant placement, while Group II comprised ten patients who received manual placements. A temporary prosthodontic was immediately inserted onto the implants, which was replaced by a permanent one after 4–6 months. ResultsThe study enrolled twenty patients. A blinded, independent assessor evaluated the outcome variables, which included implant failure, marginal bone loss, treatment duration, post-surgical pain and swelling, use of painkillers, surgical time, and patient satisfaction. Pain scores in Group II were significantly higher than those in Group I, but there were no other significant differences. All patients experienced pain after 2 days, but by 7 days, only two patients in Group I and four patients in Group II were still suffering, although this difference was not statistically significant. After 14 days, all patients were asymptomatic. ConclusionAlthough the freehand technique is straightforward for experienced surgeons, surgical guides enhance the accuracy of implant placement, particularly in a deficient alveolar ridge.

Linear bone gain and healing complication rate comparative outcomes following ridge augmentation with custom 3D printed titanium mesh vs Ti-reinforced dPTFE. A randomized clinical trial.

The aim of this randomized clinical trial was to compare the qualitative (linear alveolar ridge changes) and quantitative (healing complications) outcomes after guided bone regeneration (GBR) using a custom-made 3D printed titanium mesh versus titanium reinforced dense PTFE membrane for vertical and horizontal augmentation of deficient alveolar ridges.

Navigating Alveolar Ridge Preservation: Techniques, Materials, and Clinical Implications

Navigating Alveolar Ridge Preservation: Techniques, Materials, and Clinical Implications

Impact of labially inclined implant axes on immediate implant placement and provisionalization in anterior maxilla: A prospective cohort study.

To investigate whether a labially inclined implant axis compromises the clinical outcomes of immediate implant placement and provisionalization (IIPP) in the anterior maxilla. Patients with unsalvageable central or lateral maxillary incisors were enrolled. IIPP with simultaneous connective tissue graft (CTG) was performed in all participants. In the control group, the alveolar ridge had a long axis aligned with the tooth, which ensured that the immediate implant was aimed at the incisor edge or the cingulum of future restoration. The test group had a large angle between the axes of the ridge and tooth. To avoid bone fenestration, the implants were placed labially inclined and emerged from the labial side of future restoration. Intra-oral scanning and cone-beam computed tomography were performed to record soft and hard tissue profiles at baseline and 1 year later. Soft tissue stability, bone remodeling, and pink esthetic score (PES) were evaluated and compared between two groups. Thirty-nine participants (19 tests and 20 controls) completed the study. At 1-year post-surgery, the mid-facial gingival margin migrations were 0.85 ± 0.37 mm (test) and 0.81 ± 0.33 mm (control), without significant differences. No differences were identified in buccal profile alteration, linear ridge reduction, buccal bone thickness, or PES scores. The test group demonstrated thinner buccal soft tissue at the crestal level than the control group. When large tooth-ridge angulation presented, labially inclined implant, avoiding buccal ridge fenestration in IIPP with CTG, did not compromise the clinical outcome in short term.

Horizontal Ridge Augmentation Using Sticky Bone with Platelet-Rich Fibrin (PRF) in Anterior Maxilla Clinical and Histologic Evidence: A Case Report

Alveolar ridge deficiency is an unavoidable sequela of tooth extraction and poses major clinical challenges when reconstruction is anticipated. Various surgical approaches have been proposed to address horizontal defects, with autogenous bone grafting considered the current benchmark. However, alternative methods, utilizing tissue engineering principles and bone substitutes, offer reduced patient morbidity. This report presents an alternative case of severe horizontal bone defect augmentation in the anterior maxilla using sticky bone in conjunction with platelet-rich fibrin (PRF), and a Ti-reinforced membrane. Histologic evidence of sticky, deproteinized bovine bone material (DBBM) mixed with PRF without the use of autogenous bone is reported.

Digital workflow for graft harvest and positioning in deficient anterior mandibles versus conventional technique: Randomized controlled trial.

The cortical shell technique is frequently associated with technical drawbacks, such as the lack of anatomical guidance during shell harvest and graft. This study aims to assess the horizontal bone gain and accuracy of a digitalized protocol that incorporates two interlocking patient-specific stackable guides (PSSGs) to control the shell harvest, positioning, and fixation. Twenty patients with deficient anterior mandibles were randomly allocated; 10 patients received freehand symphyseal shell harvest and fixation (the control group), whereas the other 10 received fully guided harvest and graft (study group) using (PSSGs), the first aided an accurate shell harvest, whereas the second conveyed shell fixation. The interposition gap among both groups was loaded with an equal mix of xenogeneic and autogenous particulates. The mean radiographic bone gain among both groups was calibrated 6 months postoperatively, and the accuracy of the digital plan was assessed by superimposing and comparing the virtually planned horizontal bone dimensions with the immediate postoperative actual bone dimensions. The mean 6-month postoperative horizontal bone gain value of the study group was recorded as (4.97 ± 0.73) mm versus (4.45 ± 0.61) mm for the control group, with a statistically insignificant mean gain difference of (0.52) mm, (p = 0.101). The mean virtual preplanned horizontal bone gain was recorded (5.4 ± 0.6) versus (5.4 ± 0.6) for the immediate postoperative actual bone gain, which was also statistically insignificant (p = 0.9). The (PSSGs) provided a precise method for graft harvest, position, and fixation, resulting in satisfactory alveolar ridge dimensions with intimate accuracy.

Lateral Alveolar Ridge Augmentation with Autogenous Tooth Roots and Staged Implant Placement-5-Year Follow-Up Case Series.

Background/Objectives: Alveolar bone augmentation before implant placement is a safe and effective treatment option for the reconstruction of a deficient alveolar ridge. According to recent research, permanent teeth have been used as bone graft materials, with studies confirming their clinical and histological results. This study aimed to evaluate the efficacy of alveolar ridge augmentation with autogenous tooth roots and staged implant placement, and peri-implant tissue stability in augmented sites. Methods: A total of 20 augmentations with autogenous tooth roots on mandibular alveolar ridges in 15 patients were performed. After 6 months, the ridge width (RWa) and ridge width gain (RWg) were measured. Titanium dental implants were placed in grafted sites and loaded 10 weeks after placement. Clinical parameters (bleeding on probing-BOP; probing depth-PD; mucosal recession-MR; and clinical attachment level-CAL) were assessed 2 months (T1), 3 years (T2), and 5 years (T3) after implant loading. Results: The mean RWa was 6.71 ± 0.74 mm, and the RWg was 3.15 ± 0.54 mm, respectively. No statistically significant differences were observed for clinical parameters (BOP, PD, MR, and CAL) among different time points (p > 0.05). Conclusions: Autogenous tooth roots represent a viable solution for alveolar ridge augmentation and implant placement, providing a stable environment for peri implant tissues.

Horizontal Augmentation Using Customized Zirconia Membrane: A Case Report

Background Horizontal bone defects are frequently observed after tooth extraction, primarily resulting from the physiological resorption of the alveolar ridge. Reconstruction of horizontal defects is essential before or during dental implant placement, particularly in the esthetic zone. This case report aims to evaluate the effectiveness of horizontal alveolar ridge augmentation utilizing a customized zirconia membrane. Case Presentation A 20-year-old female patient desired to replace the missing right upper central incisor with a dental implant. The radiographic evaluation showed a concave bone defect, which makes it impossible to place a dental implant. The treatment plan was made for localized ridge augmentation using a customized zirconia membrane (CZM) prior to dental implant placement. Conclusion The customized Zirconia membrane is an effective and very satisfactory treatment option in the management of horizontal defects. Customized zirconia membranes reduce surgical time, facilitate the procedure for the patient and the practitioner, reduce the rate of complications, and achieve good horizontal bone gain.

Evaluation of Digitally Customized Titanium Mesh-Guided Alveolar Ridge Augmentation

Background: Different bone augmentation methods are used to increase the alveolar crest following the loss of one or more teeth. Guided bone regeneration is an alternative to increasing the amount of hard tissue for subsequent implant placement in the best three-dimensional position. Objectives: To evaluate the effects of bone regeneration utilizing a customized titanium mesh scaffold covered with a combination of autologous bone transplant and xenograft for the restoration of complex jaw deformities. Methods: This prospective clinical interventional study included ten patients receiving ridge augmentation of the partly edentulous mandible or maxilla after the alveolar ridge had resorbed (horizontally). A pre-surgical cone beam computed tomography (CBCT) scan was performed to assess the pre-surgical ridge size and fabricate the customized titanium mesh (CTM). A CBCT scan will be performed immediately after surgery, followed by a second CBCT scan 6 months later to measure width and volumetric analysis. Results: Both arches had a rise in volumetric gain from preoperative to postoperative, with no significant difference. Females gained more than males, although the difference was not statistically significant (males lost density after surgery). They also discovered that age, gender, and arch were not substantially associated with mesh size exposure. Conclusions: Using tailored titanium mesh scaffolds in conjunction with autogenous bone and xenografts for alveolar ridge augmentation can efficiently increase bone mass, but future research must address many limitations.

Clinical efficacy, bone density, and follow-up in implant and orthodontic treatment for inclined adjacent teeth

BACKGROUND Tooth defects can cause elongation of occlusal teeth, leading to insufficient repair space. The combination of dental implant restoration and orthodontic treatment of oblique adjacent teeth has a significant therapeutic effect. AIM To explore clinical efficacy, bone density, and follow-up of implant and orthodontic treatment for patients with inclined adjacent teeth. METHODS In total, 98 patients with oblique adjacent teeth were randomly assigned to implant restoration combined with orthodontic treatment (group A, n = 49) or to receive implant restoration alone (group B, n = 49). Changes in alveolar ridge bone density and apical bone density were observed before and after treatment in the two groups. Changes in chewing function and language function were compared between the two groups of patients. Follow-up lasted for 12 mo after repair to observe any adverse reactions in the oral cavity. RESULTS The clinical effective rates of group A and group B were 97.96% and 85.71%, respectively, with group A having a higher clinical effective rate than group B. After treatment, the bone density of the alveolar ridge and apical bone in both groups decreased compared to before treatment, while the chewing and language functions improved. The changes in various indicators in group A were more significant. After treatment, the satisfaction rate of group A (97.96%) was higher than that of group B (79.59%). The incidence of adverse reactions in group A (2.04%) was lower than that in group B (24.49%). CONCLUSION The amalgamation of implant restoration and orthodontic treatment for adjacent tilted teeth demonstrates notable clinical efficacy, diminishes alveolar bone resorption, and fosters patient functional rehabilitation while exhibiting negligible adverse reactions.

Effect of thermocycling on tensile bond strength of autopolymerized, heat-polymerized, milled, and 3D printed denture base materials bonded to 4 different denture liners: an in vitro study

BackgroundDigitally fabricated dentures may require relining due to continual alveolar ridge resorption. However, studies evaluating the tensile bond strength (TBS) of digitally fabricated dentures bonded to denture liners are lacking. This study aimed to evaluate the TBS of autopolymerized, heat-polymerized, milled, and 3D printed denture base materials bonded to 2 acrylic-based and 2 silicone-based denture liners, both before and after thermocycling. Additionally, the impact of thermocycling on the TBS were also evaluated.MethodsThe TBS of 4 different denture base materials (Palapress (PL), Vertex Rapid Simplified (VR), Smile CAM total prosthesis (SC), and NextDent denture 3D+ (ND)) bonded to 2 acrylic-based (GC Soft-Liner (GC) and Tokuyama Rebase II (RB)) and 2 silicone-based (Ufi Gel P (UP) and Sofreliner Tough M (ST)) denture liners were tested. Specimens (n = 8) were divided into non-thermocycling and thermocycling groups. Non-thermocycling specimens were tested after 24-hours water immersion, while thermocycling specimens were underwent 5000 cycle and were immediately tested. Mode of failure was examined under a stereomicroscope. Data were analyzed using 2-way ANOVA and Tukey HSD tests (α = 0.05), and independent samples t test (α = 0.05) for TBS between non-thermocycling and thermocycling groups.ResultsFor the non-thermocycling groups, within the same denture liner material, no significant differences were found between denture base materials, except the ND + RB group, which had significantly lower TBS. For the thermocycling groups, within the same denture liner material, the TBS in the PL group exhibited the highest and the ND group exhibited the lowest. Within the same denture base material, in both non-thermocycling and thermocycling groups, the TBS in the ST group exhibited the highest; in contrast, that in the GC group exhibited the lowest. No significant differences were observed in TBS between non-thermocycling and thermocycling groups, except for denture base materials bonded to the ST group, SC + UP, and ND + UP groups.ConclusionsMilled denture base can be relined with acrylic-based or silicone-based denture liner. However, cautions should be exercised when relining 3D printed denture base. Thermocycling did not affect TBS between acrylic-based denture liners and denture bases. In contrast, it affected the bond between silicone-based denture liner and denture base.

Anatomical Position of the Mentonian Foramen in Relation to the Alveolar Ridge and Mandibular Base using Cone Beam Computed Tomography in Dentate Patients

Introduction: The mentonian foramen is an important structure of the anterior part of the mandible, referent in surgical procedures of the mandible, mainly of the interforaminal area. Therefore, for a more precise analysis of this anatomical structure we use Cone Beam CT scans, since it provides us with a three-dimensional image of higher quality of the maxillofacial massif as it does not present overlapping images, geometric distortion and false negatives that could increase the risk of iatrogenic lesions. Objective: To determine the distance of the mentonian foramen in relation to the alveolar ridge and the mandibular base by means of Cone Beam Computed Tomography of dentate patients. Methodology: The study was descriptive, cross-sectional and retrospective; 109 Cone Beam Computed Tomography scans of dentate patients were evaluated from March to October 2020, taken from the Maxillofacial Diagnostic Institute (IDM) Lima, Peru; between 18 and 50 years old, distributed in three age groups: 18 to 28 years old, 29 to 39 years old and 40 to 50 years old. The distances from the upper edge of the mentonian foramen to the alveolar ridge and from the lower edge of the mentonian foramen to the mandibular base were analyzed, taking into account sex and age group. For the statistical analysis, SPSS Statistics version 26.0 was used and the T student test for related tests was applied to evaluate the differences between the right and left sides, T student for independent tests to analyze the measures with the male and female sexes and ANOVA of one factor for the analysis with the age groups. All tests were performed at a significance level of 5%. Results: The mentonian foramen is closer to the mandibular base than to the alveolar ridge, whose means are 13.81mm and 14mm, respectively. The average distance was shorter in the 40 to 50 years age group and the female sex presented shorter distances. Conclusion: The mentonian foramen is 13.81mm above the mandibular base, the greatest distances were found in the male sex and the shortest distances in the 40 to 50 years age group.

Improved new bone formation capacity of hyaluronic acid-bone substitute compound in rat calvarial critical size defect

BackgroundBone loss of residual alveolar ridges is a great challenge in the field of dental implantology. Deproteinized bovine bone mineral (DBBM) is commonly used for bone regeneration, however, it is loose and difficult to handle in clinical practice. Hyaluronic acid (HA) shows viscoelasticity, permeability and excellent biocompatibility. The aim of this study is to evaluate whether high-molecular-weight (MW) HA combined with DBBM could promote new bone formation in rat calvarial critical size defects (CSDs).Materials and methodsRat calvarial CSDs (5 mm in diameter) were created. Rats (n = 45) were randomly divided into 3 groups: HA-DBBM compound grafting group, DBBM particles only grafting group and no graft group. Defect healing was assessed by hematoxylin-eosin staining and histomorphometry 2, 4 and 8 weeks postop, followed by Micro-CT scanning 8 weeks postop. Statistical analyses were performed by ANOVA followed by Tukey's post hoc test with P < 0.05 indicating statistical significance.ResultsAll rats survived after surgery. Histomorphometric evaluation revealed that at 2, 4 and 8 weeks postop, the percentage of newly formed bone was significantly greater in HA-DBBM compound grafting group than in the other two groups. Consistently, Micro-CT assessment revealed significantly more trabecular bone (BV/TV and Tb.N) in HA-DBBM compound group than in the other two groups, respectively (P < 0.05). Moreover, the trabecular bone was significantly more continuous (Tb.Pf) in HA-DBBM compound group than in the other two groups, respectively (P < 0.05).ConclusionHA not only significantly promoted new bone formation in rats calvarial CSDs but also improved the handling ability of DBBM.

Comparison of clinical efficacy between autologous partially demineralized dentin matrix and deproteinized bovine bone mineral for bone augmentation in orthodontic patients with alveolar bone deficiency: a randomized controlled clinical trial

BackgroundIt is common to see patients who need orthodontic treatment but with insufficient alveolar bone volume. However, safe and effective tooth movement requires sufficient alveolar bone width and height. The aim of this study is to compare the bone augmentation efficacy of Autologous Partially Demineralized Dentin Matrix (APDDM) and Deproteinized Bovine Bone Mineral (DBBM) in orthodontic patients with insufficient bone by using a randomized controlled clinical trial approach.Materials and methodsTwenty-seven orthodontic patients involving 40 posterior teeth alveolar sites (n = 40) with insufficient alveolar bone volume were randomly divided into a control group (n = 20) and an experimental group (n = 20). The patients in the experimental group were treated with APDDM, and those in the control group were treated with DBBM. After surgery, the adjacent teeth are moved toward the bone grafting sites according to the orthodontic treatment plan. Patients completed a postoperative response questionnaire by the Visual Analogue Scale (VAS) score to indicate pain and swelling in the bone grafted area at the time of suture removal; and CBCT scans were conducted before surgery, 6 months and 2 years after surgery to assess changes in buccal and central alveolar heights, as well as widths at the alveolar ridge apex and 3 mm, 5 mm below the apex, respectively. The CBCT image sequences were imported into Mimics 21.0 software in DICOM format. The data of the patients in both groups were collected and analyzed by SPSS 25.0.ResultsThe VAS scores were significantly lower in the APDDM group than in the DBBM group (p < 0.05). Significant increases were observed in alveolar bone height and width at 6 months and 2 years postoperative (p < 0.05); At 2 years, the APDDM group exhibited a reduction in buccal crest height and in 3 mm, 5 mm width below alveolar ridge apex, relative to 6 months (p < 0.05), while the DBBM group showed a decrease only in the central height of the alveolar bone (p < 0.05). There was a significant bone augmentation increase found only 3 mm below the alveolar ridge apex in the APDDM group compared with the DBBM group among all 6 months group comparison (p < 0.05). At 2 years, the augmentation effects were similar across both groups (p > 0.05).ConclusionRadiomics analysis indicates that APDDM serves as a viable bone augmentation material for orthodontic patients with insufficient alveolar bone volume, achieving comparable clinical efficacy to DBBM. Additionally, APDDM is associated with a milder postoperative response than DBBM.The registration number (TRN)ChiCTR2400084607.
