Dental socket preservation

L P Zhao, Y L Zhan, W J Hu, H J Wang, Y P Wei, M Zhen, T Xu, Y S Liu
For ideal implant rehabilitation, an adequate bone volume, optical implant position, and stable and healthy soft tissue are required. The reduction of alveolar bone and changes in its morphology subsequent to tooth extraction will result in insufficient amount of bone and adversely affect the ability to optimally place dental implants in edentulous sites. Preservation of alveolar bone volume through ridge preservation has been demonstrated to reduce the vertical and horizontal contraction of the alveolar bone crest after tooth extraction and reduce the need for additional bone augmentation procedures during implant placement...

Progressive alveolar bone resorption after tooth extraction may lead to surgical and prosthetic-driven difficulties, especially when deciding to use a dental implant to replace the extracted tooth. This case report discusses an irreparable lower left second premolar tooth with a periodontal lesion on the buccal side. A preservative tooth extraction was performed. Then, the socket was grafted with bovine bone, a collagen membrane was placed between the buccal bone and the attached gingiva, covering the bone dehiscence buccally, and the socket without a flap was raised...

BACKGROUND: To date, limited evidence is available specifically evaluating ridge preservation (RP) and implant placement in molar sites. The primary aim of this study was to radiographically compare alveolar ridge changes with and without RP with cone-beam computed tomography (CBCT). METHODS: This parallel, two-arm RCT included forty patients evenly distributed between two treatment groups. Following molar extraction, sites were allowed to heal naturally or received RP with freeze-dried bone allograft covered by a non-resorbable dense polytetrafluoroethylene (dPTFE) membrane...

BACKGROUND: A common sequel of tooth extraction is alveolar bone resorption. It makes the placement of dental implants difficult and creates an esthetic problem for the fabrication of conventional prostheses. Therefore, alveolar bone following tooth extraction should be preserved. AIMS AND OBJECTIVES: The present prospective study was conducted to evaluate the efficacy of the resorbable bioscaffold poly lactic co-glycolic acid (PLGA) in maintaining the alveolar height in post-extraction socket...

To ensure a successful dental implant therapy, the presence of adequate vertical and horizontal alveolar bone is fundamental. However, an insufficient amount of alveolar ridge in both dimensions is often encountered in dental practice due to the consequences of oral diseases and tooth loss. Although postextraction socket preservation has been adopted to lessen the need for such invasive approaches, it utilizes bone grafting materials, which have limitations that could negatively affect the quality of bone formation...

BACKGROUND: In implant dentistry, bone substitute materials and barrier membranes are used in different treatments including guided bone regeneration (GBR), socket preservation, alveolar ridge augmentation, maxillary sinus elevation, and filling bony defects around the inserted dental implant. One of the most important factors in prognosis of treatments using these materials is the growth of new blood vessels in applied areas. Present review was performed to evaluate the effect of the bone-grafting and barrier membrane materials on angiogenesis events...

AIM: Ridge preservation is any procedure that takes place at the time of, or shortly after an extraction, to minimise resorption of the ridge and maximise bone formation within the socket. The aim of this project is to investigate the outcome of implant treatment following ridge preservation and compare it to an ungrafted implant control group. METHODS AND MATERIALS: Following ethics approval, an electronic and manual search of patient records was conducted, and appropriate cases of implant placement following a ridge preservation procedure were identified...

INTRODUCTION: A case series was used to evaluate the efficacy and predictability of a ceramic matrix in a putty-like collagen carrier in immediate extraction sockets. METHODS: A single failing tooth was atraumatically extracted from each of 10 subjects. The sockets were debrided and grafted with ceramic matrix in a putty-like collagen carrier (15% hydroxyapatite, 85% β-tricalcium phosphate complex). A bovine pericardium membrane was draped over the graft site and a tension-free primary closure was obtained...

To evaluate the effects of alveolar ridge preservation with Bio-Oss bone substitute (Geistlich Pharma) on delayed implant osseointegration. The 3rd and 4th left and right mandibular premolars were extracted from four adult healthy male and female dogs. For the experimental group, we randomly selected two extraction sockets in each dog to be filled with Bio-Oss bone substitute (Geistlich Pharma). The two remaining extraction sockets remained untreated and served as the control group. Three months after Bio-Oss placement, dental implants were inserted into the alveolar bone of the experimental group and the control group...

Volumetric changes of the alveolar ridge after socket preservation with various techniques have been investigated frequently. However, changes in bone density and quality of bone within the extraction sockets have seldom been studied. The purpose of this study was to evaluate the bone quality of grafted versus non-grafted socket sites prior to dental implant placement using Hounsfield unit (HU) values derived from cone-beam computed tomography (CBCT) imaging. The data was collected from 39 healed extraction sites reviewed over a one-year period...

The aim of this study was to evaluate the clinical relevance of autogenous fresh demineralized tooth (Auto-FDT) prepared at chairside immediately after extraction for socket preservation. Teeth were processed to graft materials in block, chip, or powder types immediately after extraction. Extraction sockets were filled with these materials and dental implants were installed immediately or after a delay. A panoramic radiograph and a conebeam CT were taken. In two cases, tissue samples were taken for histologic examination...

Restoring failing anterior teeth with a dental implant is considered a complex treatment even with thorough biologic knowledge of the situation. The goal is to produce a result in which the labial soft tissues and the papillae remain stable over time. Treatment of the fresh extraction socket in the alveolar ridge presents a challenge in everyday clinical practice. Regardless of the subsequent treatment, maintenance of the ridge contour will frequently facilitate all further therapeutic steps. Socket seal surgery and socket preservation in combination with immediate, early, or delayed implant placement can be valuable procedures for single tooth replacement...

The clinician is often asked to remove a tooth and place an implant into the site. The implant must be placed with appropriate stability to allow for integration to occur, which requires bone presence. Bone is also necessary to allow for ideal implant positioning within the alveolus for functional and esthetic concerns. The purpose of this article is to discuss the changes in socket dimensions over time and how to promote space maintenance, with an algorithm for treatment based on evidence.
