Extraction Socket Preservation with or without Membranes, Soft Tissue Influence on Post Extraction Alveolar Ridge Preservation: a Systematic Review.

ABSTRACT: Objectives:The purpose of this systematic review was to assess quantitatively and qualitatively the influence of two different factors: membranes and soft tissue graft influence for the extraction socket preservation. Material and Methods:A wide-ranging electronic search was performed in six databases up to 30 of November 2018 in order to identify all the clinical and randomized clinical trials performed in humans published with no data restriction. The inclusion criteria were extraction socket preservation with and without membranes or a soft tissue graft in a intact socket with at least six months of follow-up, have more than 12 patients or treat more than 12 sites per group and evaluated at least one of the primary outcomes measures (radiographic measures histological assessment, clinical measures). Results:From an initial search of 1524 studies only 6 papers fulfil the inclusion and exclusion criterions. All the six selected papers, presented a wide heterogeneity of treatments used, evaluated variables and observation period that made impossible to recommend any specific techniques and/or material to achieve better results. The limited data found suggest that the used of membrane reveals to achieve better results. It wasn't possible to observe in any clinical trial that compares the used of soft tissue graft. Conclusions:New trials need to be performed in order to identify what specific techniques and/or materials are better to decrease the reabsorption of the socket after tooth extraction. Clinical trials designed to understand when/how the soft tissues grafts influence at the socket preservation is needed.

Project description:Tooth extraction results in alveolar bone resorption and is accompanied by postoperative swelling and pain. Maresin 1 (MaR1) is a proresolving lipid mediator produced by macrophages during the resolution phase of inflammation, bridging healing and tissue regeneration. The aim of this study was to examine the effects of MaR1 on tooth extraction socket wound healing in a preclinical rat model. The maxillary right first molars of Sprague-Dawley rats were extracted, and gelatin scaffolds were placed into the sockets with or without MaR1. Topical application was also given twice a week until complete socket wound closure up to 14 d. Immediate postoperative pain was assessed by 3 scores. Histology and microcomputed tomography were used to assess socket bone fill and alveolar ridge dimensional changes at selected dates. The assessments of coded specimens were performed by masked, calibrated examiners. Local application of MaR1 potently accelerated extraction socket healing. Macroscopic and histologic analysis revealed a reduced soft tissue wound opening and more rapid re-epithelialization with MaR1 delivery versus vehicle on socket healing. Under micro-computed tomography analysis, MaR1 (especially at 0.05 μg/μL) stimulated greater socket bone fill at day 10 as compared with the vehicle-treated animals, resulting in less buccal plate resorption and a wider alveolar ridge by day 21. Interestingly, an increased ratio of CD206+:CD68+ macrophages was identified in the sockets with MaR1 application under immunohistochemistry and immunofluorescence analysis. As compared with the vehicle therapy, local delivery of MaR1 reduced immediate postoperative surrogate pain score panels. In summary, MaR1 accelerated extraction wound healing, promoted socket bone fill, preserved alveolar ridge bone, and reduced postoperative pain in vivo with a rodent preclinical model. Local administration of MaR1 offers clinical potential to accelerate extraction socket wound healing for more predictable dental implant reconstruction.

Project description:Background:The healing process following tooth extraction results in alveolar ridge resorption. The dimensional changes may complicate the subsequent implant procedure. Socket preservation using absorbable collagen membranes or a combination of membranes with calcium phosphate cement (CPC) particles might ensure that the alveolar ridge retains a suitable morphology for implant placement. Objective:To evaluate the quality and quantity of new bone regenerated after application of either collagen membranes alone covering the sockets or a combination of membranes with CPC particles added into the sockets in dogs. Materials and Methods. Six dogs were included in this study. The mandibular premolars were extracted. For each hemimandible, three premolar extraction sites were randomly assigned to one of the following treatments: a covering collagen membrane, CPC with a covering collagen membrane, and a socket left empty. Cone-beam computed tomography (CBCT) measurements, polyfluorochrome sequential labeling, and histological assessments were performed to investigate the healing ability and repair processes within a 6-month observation period. Results:Buccal bone height in the membrane group was significantly higher than that in the membrane+CPC and blank groups at 4 and 6 months after extraction. The mineral apposition rate over 2-4 months and the alizarin red-stained area in the membrane group were significantly higher than those in the other two groups. Histological analysis after 6 months of healing showed significantly higher amounts of newly formed bone in the membrane group than in the other groups. Conclusion:Extraction sites treated with collagen barrier membranes showed better protection than sites not covered with membranes. And the buccal bone wall of the socket was well preserved by collagen membrane without extra CPC materials. Socket preservation using absorbable membranes alone yielded better quality and quantity of regenerated bone inside the socket site.

Project description:ObjectiveThe objective of this study is to retrospectively evaluate the clinical outcomes of alveolar ridge preservation (ARP) in the compromised extraction sockets using autogenous cortical-lamina anchoring technique (CAT).Material and methodsTwenty patients were treated with ARP in the compromised extraction sockets by applying CAT. Then implant placement and crown delivery was performed. A planned follow-up was performed by analyzing various outcome measures to evaluate the clinical outcomes, including primary outcome measures [radiographic assessment of residual alveolar ridge height (RARH) and residual alveolar ridge width (RARW)] and secondary outcome measures [clinical assessment of the healing of the soft and hard tissue, survival rates of implants, marginal bone loss (MBL) evaluation of implants, buccal bone thickness (BBT), and esthetic treatment outcomes].ResultsAmong the 20 patients, 17 were consecutively treated and 3 dropped out after implant crown delivery because of loss to follow-up. After the ARP, the initial RARH (12.37 mm) significantly increased to 19.29 mm (P < .05). No significant difference was detected in the RARW before (7.92 ± 1.18 mm) and after (7.92 ± 1.18 mm) the ARP, but reduce to 6.99 ± 1.18 mm at the implant placement and 6.64 ± 0.77 mm at the 3-year follow-up (P < .05). The MBL at the implant crown delivery (0.13 ± 0.12 mm) significantly increased to 0.31 ± 0.14 mm at 1-year follow-up and 0.56 ± 0.23 mm at 3-year follow-up, respectively. The bone loss was limited (<1 mm) but statistically significant (P < .05). The BBT at the implant placement (2.53 ± 0.56 mm) significantly reduced to 2.23 ± 0.44 mm at implant crown delivery and 2.14 ± 0.40 mm at 3-year follow-up, respectively. The bone loss was also limited (<0.5 mm) but statistically significant (P < .05). Each implant site showed acceptable aesthetic outcome and the average score was 16.4. The incisions healed uneventful in all patients and the implant survival rate was 100% during the 3-year follow-up.ConclusionAutogenous CAT was successfully applied to preserve the height and width of alveolar ridge in the compromised extraction sockets.
