Guided immediate implant with and without using a mixture of autogenous and xeno bone grafts in the dental esthetic zone. A randomized clinical trial

PurposeThis in vivo study aims to assess the pink esthetic score in the anterior maxilla after computer-guided immediate implant installation and fully digital immediate temporalization with and without grafting the jumping gap with a mixture of 1:1 autogenous and xenograft particulates.Materials and methodsTwenty-four patients with non-restorable upper anterior teeth in the aesthetic zone have undergone a traumatic extraction for the non-restorable tooth followed by immediate implant placement using a 3D-printed surgical guide according to prosthetically driven implant placement. The patients were divided into two groups. The study group received the dental implant after grafting the jumping gap with 1:1 autogenous and xenograft particulates, while the control group received the dental implant without grafting the jumping gap. Each patient received a digitally fabricated, immediate, nonfunctional temporary prosthesis. The esthetic outcome was compared between the two groups using the pink esthetic score at implant insertion and after 6 months of follow-up. Statistical comparisons were carried out between the studied groups using the Mann-Whitney U test.ResultsImmediately postoperatively, there was no statistically significant difference between the median PES in the two groups (P-value = 0.746). After six months, the study group showed a statistically significantly higher median PES than the control group (P-value = 0.048).ConclusionsGrafting the jumping distance in the immediate implant protocol helps achieve a better esthetic outcome.Clinical relevanceThe use of immediate guided implant placement along with grafting the jumping gap followed by immediate digital temporalization guarantees a better esthetic outcome while preserving time, cost, and the number of clinical visits.Trial registrationThe study was registered on clinicaltrials.gov with registration number NCT04096209.

Evaluation of different surface treated implants after provisionalization: A 6-month prospective study.

Replacing missing teeth with dental implants has become the best treatment option; therefore, clinicians need to understand the predictability of the treatment. Surface treatment of implants is one of the methods to improve osseointegration, thus improving the quality of treatment. Increasing esthetic awareness among patients has led to the popularity of immediate provisionalization of dental implants. This study investigated the effect of surface treatment on implant stability when loaded with immediate non-functional temporary prostheses and compared the superiority of one surface treatment over the other in terms of osseointegration by evaluating implant stability quotient (ISQ). Twenty implants with different surface treatments were placed, i.e., resorbable blast media (RBM) surface and alumina blasted/acid-etched (AB/AE) surfaces. All the implants were non-functionally loaded, and ISQ was measured immediately after implant placement and 6 and 12 weeks after non-functional loading. Crestal bone levels, mPI, mSBI, and peri-implant probing depths were compared for both groups at 1, 3, and 6 months. At 12 weeks, all the implants showed desirable ISQ, indicating successful osseointegration. The increase in ISQ at 12 weeks was significantly higher for RBM implants compared to baseline, indicating a more predictable course of osseointegration. Crestal bone levels recorded at 1, 3, and 6 months did not significantly differ between the groups. All other parameters showed comparable values for both groups at all intervals. Replacing missing teeth with dental implants with immediate non-functional restorations is a predictable treatment option.

The Effect of Thermo Cycling on Fracture Resistance Of Temporary Prosthesis Fabricated By CAD/CAM With Composite- Based Material

Aim: The objective of this study was to evaluate the effect of thermo cycling on fracture resistance of temporary prosthesis constriction by computer-aided design/ computer-aided manufacturing (CAD/CAM) with those of composite materials. Material and Methods: A dentoform maxillary molar tooth was prepared for full coverage crown, temporary prosthesis was constriction and divided into the following groups: CAD/CAM poly (methyl methacrylate) (PMMA) blocks, and auto- polymerizing temporary material. All specimens were subjected to thermo cycling and then fracture strength was measured by a universal testing machine. Results: The mean ± Stander deviation values for CAD CAM group before thermo cycling (560.50 ±83.581 Newton) and after thermo cycling (901.00± 311.598 Newton) were recorded statistically significant higher fracture resistance mean compared with composite fabricated interim restorations. Conclusion: Interim prosthesis constructed using CAD CAM technique showed higher fracture

Digital Workflow in Full Mouth Rehabilitation with Immediate Loading, Intraoral Welding and 3D-Printed Reconstructions in a Periodontal Patient: A Case Report

Background: Complex implant reconstructions in patients with residual dentition due to periodontitis is a challenging task in many aspects. Methods: This study shows a full digital workflow combining 3D printing, guided implant placement, intraoral scanning and welding with immediate loading and digital smile design. An analog impression was taken to validate the passive fit of final restorations. The whole treatment plan was divided into three stages. The first stage included an intraoral scan of baseline dentition, and then the extraction of all teeth was performed, implanting four temporary implants and providing the patient with removable temporary prosthesis. The second stage was to scan the removable temporaries, implanting 10 implants and multi-unit abutments (MUA), and create a rigid construction via the intraoral welding of titanium bar and by fixing it to the 3D-printed temporary reconstructions (designed with DSD) as a form of immediate loading. The third stage included the scanning of screw-retained temporary reconstructions, then scanning from the MUA level and creating final reconstruction. Results: The presented workflow enabled the delivery of some sort of restoration to the patient at every moment of the treatment and to sustain the required esthetic effect with decent comfort of use even in the early stages. Conclusions: A full digital workflow is a reliable treatment method even in complex cases.

Shear Strength of Repaired 3D-Printed and Milled Provisional Materials Using Different Resin Materials with and without Chemical and Mechanical Surface Treatment.

The aim of this study was to assess the shear bond strength of 3D-printed and milled provisional restorations using various resin materials and surface finishes. There were 160 preliminary samples in all, and they were split into two groups: the milled group and the 3D-printed group. Based on the resin used for repair (composite or polymethylmethacrylate (PMMA)) and the type of surface treatment utilized (chemical or mechanical), each group was further divided into subgroups. The specimens were subjected to thermocycling from 5 °C to 55 °C for up to 5000 thermal cycles with a dwell time of 30 s. The mechanical qualities of the repaired material underwent testing for shear bond strength (SBS). To identify the significant differences between the groups and subgroups, a statistical analysis was carried out. Three-way ANOVA was used to analyze the effects of each independent component (the material and the bonding condition), as well as the interaction between the independent factors on shear bond strength. Tukey multiple post-hoc tests were used to compare the mean results for each material under various bonding circumstances. The shear bond strengths of the various groups and subgroups differed significantly (p < 0.05). When compared to the milled group, the 3D-printed group had a much greater mean shear bond strength. When compared to PMMA repair, the composite resin material showed a noticeably greater shear bond strength. In terms of surface treatments, the samples with mechanical and chemical surface treatments had stronger shear bonds than those that had not received any. The results of this study demonstrate the effect of the fabrication method, resin type, and surface treatment on the shear bond strength of restored provisional restorations. Particularly when made using composite material and given surface treatments, 3D-printed provisional restorations showed exceptional mechanical qualities. These results can help dentists choose the best fabrication methods, resin materials, and surface treatments through which to increase the durability and bond strength of temporary prosthesis.

Review Article on the All-On-Four Treatment Concept in Dental Implants

Edentulism, a condition characterized by the absence of teeth, significantly impacts facial aesthetics, eating efficiency, and speech fluency, thereby diminishing the quality of life. This paper aims to explore the All-On-Four Treatment Concept in Dental Implants, a promising solution to this issue. The All-On-Four approach, though complex, offers a pathway to restore smile and functionality by using four strategically positioned implants to hold a temporary prosthesis. This prosthesis is later replaced by a permanent version after approximately four months. This swift oral restoration technique significantly enhances a patient’s self-confidence and overall life quality. The significance of this treatment lies in its potential to provide a less invasive and more affordable solution for severe jawbone atrophy, where the proximity of critical anatomical structures and compromised bone conditions may hinder other prosthetic solutions. The paper concludes with a discussion on the potential of the All-On-Four treatment to revolutionize dental implant procedures, offering a beacon of hope for individuals suffering from edentulism.

Fabrication of a Closed Hollow Bulb Obturator for the Rehabilitation of an Acquired Partial Maxillectomy Defect Due to Mucormycosis

Patient affected from post-COVID mucormycosis often require local debridement or surgical resection resulting in maxillectomy. This is frequently quite extensive or bilateral and spares very little of the hard and soft tissues in the oral cavity. Both surgery and prosthetic rehabilitation are needed to rehabilitate such extensive defects. Once the patient has grown accustomed to the temporary prosthesis and effective healing has taken place, a definitive prosthesis is inserted for the patient. Definitive obturators require careful thought during design to ensure longevity and superior retention and stability. This article documents the prosthetic rehabilitation of a partial maxillectomy defect due to mucormycosis which resulted after COVID.

Evaluation of Biomechanical Stability of Teeth Tissue According to Crown Materials: A Three-Dimensional Finite Element Analysis.

The biomechanical effects of dental tissue according to various dental crown materials were investigated using finite element analysis. Bone, prepared tooth, root canal, and periodontal ligament were modeled based on computed tomography. Depending on the characteristics of the crown material, it was classified into zirconia, hybrid ceramic, gold alloy, and acrylic resin. A loading force of 200 N was applied in the vertical direction to the occlusal surface of the crown, and analysis was performed under the condition that all interfaces were tied. The results demonstrate that the highest von Mises stress was shown in the prepared tooth of the acrylic resin model, which is a temporary prosthesis, and the pulpal pressure was also the highest. Additionally, among the final prosthesis, the highest stress was shown in the hybrid ceramic model prepared teeth. The properties of restoration materials can be a factor influencing the tooth structure. Thus, in order to make a correct decision when selecting a material for restorative treatment, it is necessary to understand, analyze, and evaluate the properties of these restoration materials.

Physical, Mechanical, and Biological Properties of PMMA-Based Composite Bone Cement Containing Silver-Doped Bioactive and Antibacterial Glass Particles with Different Particles Sizes.

In the present work, antibacterial composite bone cement was designed by introducing a bioactive and antibacterial glass into a commercial formulation. The effect of glass particles' addition on the curing parameters of the polymeric matrix was evaluated; moreover, the influence of the glass particle size on the glass dispersion, compressive and bending strength, bioactivity, and antibacterial effect was estimated. The results evidence a delay in the polymerization kinetics of the composite cement, which nevertheless complies with the requirements of the ISO standard. Morphological characterization provides evidence of good dispersion of the glass in the polymeric matrix and its exposition on the cement surface. The different glass grain sizes do not affect the composites' bioactivity and compressive strength, while a slight reduction in bending strength was observed for samples containing glass powders with greater dimensions. The size of the glass particles also appears to have an effect on the antibacterial properties, since the composites containing larger glass particles do not produce an inhibition halo towards the S. aureus strain. The obtained results demonstrate that, by carefully tailoring the glass amount and size, a multifunctional device for artificial joint fixing, temporary prostheses, or spinal surgery can be obtained.

Evaluation of Prosthetic Marginal Fit and Implant Survival Rates for Conventional and Digital Workflows in Full-Arch Immediate Loading Rehabilitations: A Retrospective Clinical Study.

Digital impression provides several advantages in implant prosthodontics; however, its use in full-arch rehabilitations, especially immediately after surgery, has yet to be validated. The aim of this study was to retrospectively analyse the fit of immediate full-arch prostheses, fabricated using conventional or digital impressions. Patients requiring a full-arch immediate loading rehabilitation were divided into three groups: T1 (digital impression taken immediately after surgery), T2 (Preoperative digital impression, guided surgery-prefabricated temporary bridge) and C (conventional impression taken immediately after surgery). Immediate temporary prostheses were delivered within 24 h after surgery. X-rays were obtained at the time of prosthesis delivery and at the 2-year follow-up. Primary outcomes were cumulative survival rate (CSR) and prosthesis fit. Secondary outcomes were marginal bone level (MBL) and patient satisfaction. One hundred and fifty patients were treated from 2018 to 2020, with 50 in each group. Seven implants failed during the observation period. The CSR was 99% for T1, 98% for T2 and 99.5% for C. A statistically significant difference in prosthesis fit was found among T1 and T2 vs. C. A statistically significant difference was found in the MBL between T1 and C. The outcomes of the present study suggest that digital impression is a viable alternative to conventional protocols for the realisation of full-arch immediate loading prostheses.

Survival rate of dental implants installed by postgraduate students attending an implantology program in Brazil: A 52-month retrospective analysis

ObjectivesThe aim of this study was to assess the survival rate and identify possible risk factors for failure of dental implants placed by postgraduate students in Implantology at a Brazilian Dental School.Materials &amp;amp; methodsA retrospective observational study was conducted to evaluate 1,164 dental implants placed by postgraduate students in Implantology at São Leopoldo Mandic Dental School (Brazil) during a 3-year time period (2018–2020). Data collected from the patients' medical charts included the following: implant loss, gender, diabetes, smoking, continuous use of medication, type of implant connection system, implant position (maxilla or mandible), previous bone grafting and type of prosthetic provisioning (temporary prosthesis, immediate prosthesis or permanent prosthesis). The association between all the independent variables and implant loss was run using χ2 and G tests (α = 5%). The implant survival rate was estimated using Kaplan-Meier curve.ResultsGender, diabetes, smoking, continuous use of medication, type of implant connection system, implant position, previous bone grafting and type of prosthetic provisioning showed no statistically significant association with implant loss. Of the 1,164 implants installed, 29 (2.5%) failed. The overall survival rate of dental implants placed by postgraduate students up to 52 months was 90.5% (IC95%: 74.5%–96.7%).ConclusionsImplants placed by postgraduate students in Implantology at São Leopoldo Mandic Dental School showed a high survival rate, with gender, diabetes, smoking, continuous use of medication, type of implant connection system, implant position, previous bone grafting and type of prosthetic provisioning not accounting for the risk of implant failure.

Stackable guide in implantology: A technical note

IntroductionWith the rise of digital workflow, the production of implant guides is becoming increasingly easy and reproducible. The objective is to obtain an optimal correlation between the prosthetic and implant axis to ensuring the “X jaw – one day” concept in the short term and a sustainable technique in a long term TechniqueThis approach requires a strict and rigorous preoperative evaluation. The data recording steps allow a complete visualization of the case and are used to custom the guide. The bone support is surmounted by several stages (positioning guide, drilling guide and the future temporary prosthesis). ConclusionDespite the time-consuming nature, this technique provides a reliable and reproducible protocol for immediate loading without compromising the prosthetic axis.

Comparative Evaluation of the Crestal Bone Level Around Pre- and Post-loaded Immediate Endoosseous Implants Using Cone-Beam Computed Tomography: A Clinico-Radiographic Study.

Introduction Dental implants replacemissing teeth. Dental implants are surgically placed tooth root replacements that secure prosthetic teeth and bridges. Branemark's original dental implant technique included a mesiobuccal flap and a two-stage approach, needing 6-8 months of recovery following extraction, sterile conditions, machined titanium implants, 3-6 months without stress for osseointegration, and a detachable temporary prosthesis. The restoration would usually be ready a year following the implant surgery. Implant treatment seeks the best function, aesthetics, and complication risk. Implant therapy with low patient morbidity and fast extraction-to-restoration times is asecondary target. Instantaneous implant insertion has made implant dentistry more convenient for patients and clinicians. This study measures bone height before, after, and one month after implant placement using cone-beam computed tomography (CBCT). Materialsand Methods Participants were selected from oral evaluation candidates. This investigation included 11 people missing front maxillary or mandibular teeth or root components. Diagnostic castings determined the interarch connection before surgery. Alginate maxillary and mandibular arch imprints were cast in Type III dental stone for diagnosis. CBCT scans were taken pre-operatively, post-implant, and post-prosthesis. After the tooth was removed, the empty socket was cleaned up with curettes. An intraoral periapical radiographand manual probing were done to determine the implant's size. The implant was removed for examination after three months, and healing abutments and gingival formers were placed. Finally, fins were placed. The CBCT images also captured the bone height around the implants. The soft tissue parameters were recorded and evaluated at baseline and one-month following prosthetic loading as plaque index (PI). Radiographic evaluation was done at baseline and one-month following functional loading using CBCT. After one month following functional loading, crestal bone levels were measured again with the help of CBCT using Image J software (National Institutes of Health, Bethesda,Maryland, US). Results The sample population had an average age of 42.81 years, with a standard deviation of 13.44 years. Using a paired t-test, we found that the mean PI dropped significantly from pre-loading levels to one-month post-loading levels, with a p-value of less than 0.001. The mean crestal bone level (mesial) evaluated by CBCT at baseline and one-month post-loading was 2.52 ± 1.97 mm and 1.17 ± 1.31 mm, respectively. The mean difference between mean crestal bone loss (distal) at baseline and one-month post-loading was 0.94 ± 1.89 mm, which was not statistically significant. The mean difference between mean crestal bone loss (buccal) at baseline and one-month post-loading was 1.82 ± 1.60 mm, which was statistically significant. The mean difference between mean crestal bone loss (lingual) at baseline and one-month post-loading was 1.91 ± 1.53 which was statistically significant. Conclusion CBCT provides all the diagnostic data needed for implant placement; hence, it is recommended.

Clinical Advances in Implant Transmucosal Contouring for Single Implant Sites: Prosthetic and Biologic Considerations.

Current evidence suggests that proper implant transmucosal contouring can significantly impact supracrestal soft tissue development and crestal bone response both in early and late stages of treatment. The macrodesign and composition of the anatomical healing abutment or temporary prosthesis used during transmucosal contouring are crucial elements for establishing biologic and prosthetic conditions that minimize early bone remodeling, improve esthetic outcomes, and reduce the possibility for future peri-implant inflammation. This article presents clinical directions on the design and fabrication processes of anatomical healing abutments or temporary prostheses for single implant sites under the interpretation of currently available scientific data.

Immediate Implants, Immediate Loading, and Milled Double Bar Prosthesis (Titanium, Biohpp): A Case Report

Abstract To rehabilitate lower arch by placing immediate implants and immediate milled provisionals and provide double bar prosthesis for the long-term survival of implants. Full-mouth rehabilitation by integrating cone-beam computed tomography data three-dimensional printing technology helps in precise placement and predictable outcomes to the longevity of implants. Six immediate implants were placed in the lower arch using digitally guided surgery. Computer-aided design-computer-aided manufacture milled temporary prosthesis was also given within 24 h of the surgery. After allowing for osseointegration, the final prosthesis was made up of materials such as titanium (primary bar), PEEK (secondary bar), and high-impact polymer composite crowns. Splinting all the implants together with such framework designs reduces the loads on implants and addition of two bars produces a dampening effect and helps long-term survival of the same. Strategies used to preserve alveolar bone and soft tissue by immediate implant placement in fresh extraction sockets shorten the treatment span. Immediate loading of implants using temporary prosthesis can be done after attaining adequate primary stability. This case has a follow-up of 6 years. The milled double bars made out of titanium and BioHPP h provide dampening effect and thus long-term survival of the implant.

Navigating the clinical ambiguity of implant placement in two young pubescent patients: an insight from two case reports

The horizon of implant dentistry has been ever-expanding owing to its long-term success in rehabilitating partially or completely edentulous cases. This perennial success and efficiency have encouraged clinicians to use osseo-integrated implants to replace teeth lost in children either due to trauma or congenital absence. Although a myriad of studies and publications suggest the placement of implants only after the attainment of skeletal maturity, as the growth-related changes such as remodelling, displacement, and mesial drift can put the future of implant and restoration in jeopardy, the use of implants in young pubescent or adolescent looks promising due to its evident psychological and social advantages over other contemporary alternatives such as a removable prosthesis or resin-bonded bridge. The first case report highlights a 16-year follow-up of a young girl treated at the age of 10 with an implant-supported prosthesis for the replacement of a missing maxillary left central incisor. The second case report centers around a 19-year-old teenage girl who underwent rehabilitation with a permanent fixed prosthesis, replacing her previous implant-supported temporary prosthesis. The implant was initially placed when she was 10 years old.

Comparison of shear bond strength between various temporary prostheses resin blocks fabricated by subtractive and additive manufacturing methods bonded to self-curing reline resin

Copy-paste concept: Full digital approach in the management of gingival emergence profiles.

Obtaining a perfect integration of a prosthetic rehabilitation on natural teeth and implantys in the esthetic zone requires a deep knowledge of the biological processes and a clear understanding of the characteristics of the restorative materials. Once the soft tissue profile has been created with the placement of a temporary prosthesis, the ability to accurately transfer information about the tissue profile and the contour of the restoration for the fabrication of the definitive crowns can be challenging. This paper illustrate the copy paste full digital workflow, a simple protocol that allows to create definitive restorations by making an exact copy of the temporary prosthesis that has been placed in function in the patient's mouth.

Clinical Outcome of Immediate Loading UV-Photofunctionalized Implants in Patients with Completely Edentulous Mandible, Placed with Guided Surgery.

The purpose of this study was to evaluate clinical results of immediate loading UV-photofunctionalized dental implants placed using guided surgery in patients with completely edentulous mandible. In this study, 58 fully edentulous patients were treated with immediate loading implant-supported mandibular prostheses. All patients underwent a thorough clinical examination according to the generally accepted scheme; qualitative and quantitative parameters of the jaw bones patients were diagnosed with cone beam computerized tomography (CBCT). Surgical templates modeled in the 3 Shape software were made from biocompatible polymeric materials and provided with depth-calibrated drill sleeves for preparing osteotomies using a 3D printer (Stratasys). Before short implant placement, ultraviolet functionalization of implant surfaces was performed by UV Activator YWJ-QSY001 (Foshan, Wenjian Medikal Enstriman) in the device for 20s. After flapless surgery, implant sockets were prepared with guided surgery and implants were placed through the sleeves of the surgical template tightening torque of 35-45 Ncm. An implant-supported temporary prosthesis made of acrylic resin was installed 6h after implantation. Final dental prosthetics was performed 2months after implant placement.The patients had 128 short (length 5-6mm, diameters 4,5-5mm) and 256 implants with length greater than 10mm in bone segments with sufficient bone parameters. The following parameters were assessed: implant success, prosthetics survival and changes in peri-implant marginal bone loss(MBL). During a clinical examination, no serious biological or prosthetic complications have been reported. The esthetic result evaluated from patients was excellent. The mean ISQ of short implants was 69.2 ± 8 for primary stability at implant placement and 73.6 ± 4 ISQ after 3months. The mean of implants with length greater than 10mm was 71,2ISQ at implant placement, respectively, and 75,6 ISQ after 3months. After 3months of prosthetic loading for short implants marginal bone loss (MBL) 0.74mm, after 1year of MBL 11.21mm, after 5years of MBL 1,37mm, for implants with length greater than 10mm after 3months of MBL 0.72mm, after 1year of MBL 1.19mm and after 5years of MBL 1.35. There was no statistically significant difference in clinical indices between short and standard implants. After 5years of follow-up, stable levels of bone tissue around the implants and healthy tissues around the implants were recorded, and postoperative occlusal function was favorable. The success rates of the short implants in maxilla were 95.5%, and the success rates of the short implants in mandible were 98.7%. The success rates of the implants with length greater than 10mm in maxilla were 97.8%, and the success rates of the implants with length greater than 10mm in mandible were 98.8%. Computer-guided implant surgery and immediate loading of UV-photofunctionalized implants in patients with completely edentulous mandible are a predictable and effective method with a minimum rehabilitation period.

Effect of glaze and chlorhexidine on physical and mechanical properties of bis-acryl resin: An in situ study.

Temporary prosthesis protects the oral tissues, in addition to providing aesthetic look and masticatory function until a definitive prosthesis is manufactured. To evaluate the effect of glaze and 0.12% chlorhexidine (CHX) on the physical and mechanical properties of bis-acryl, and to evaluate the antimicrobial efficacy of CHX. Eighty specimens of bis-acryl resin were made. Over 40 of them the glaze was applied. One specimen with and 1 specimen without glaze were placed in niches of an appliance manufactured for each patient. Each of the 20 volunteers received 2 devices. Initially, the volunteers used one device and treated it with sucrose for 7 days (control), and later they used the other device and treated it with sucrose and CHX for 7 days (test). Color, microhardness, roughness, surface energy, and insoluble extracellular polysaccharides (EPS) tests were performed. All results were submitted to the Tukey's test, with the exception of the EPS results, which were submitted to the Student's t test. The ΔE00 of the unglazed control group was significantly higher than that of the unglazed test group. In all groups, a significant decrease in microhardness occurred over time. At both times, the glaze significantly increased the microhardness of the specimens (in all the glazed groups). At the final time, the test glaze group showed significantly higher microhardness compared with the control glaze group. Roughness in the groups without glaze increased significantly with CHX treatment over time. At both times, the glaze generated a significant reduction in roughness in the control and test groups. There was a significant reduction in surface energy over time in all groups. In most comparisons, the glazed groups showed significantly higher surface energy values compared with the unglazed control group. At the final time point, the unglazed test group showed a significantly higher surface energy value than the unglazed control group; and the glazed test group showed a significantly higher surface energy value compared with the glazed control group. The resins that received CHX had a significantly lower amount of biofilm. Color values were clinically acceptable in all tested groups. At both time points, the roughness values were clinically acceptable only in the glazed groups. Glaze increased the microhardness of the specimens. Microhardness and surface energy were reduced over time in all groups. Chlorhexidine can help prevent microhardness degradation. Glaze and CHX can increase surface energy. Chlorhexidine reduced the amount of bacterial biofilm.
