Horizontal bone augmentation

When considering placing dental implants in atrophic edentulous sites, there may be inadequate site width and little or no vertical bone loss. Any of several surgical procedures can augment these sites. Extracortical augmentation is done by applying graft material against the cortical bone. This technique expects progenitor cells to migrate outside the bony ridge's confines and form new bone. Another method entails ridge splitting and expansion to create space for osteogenesis and, when possible, implant placement...

Bone augmentation techniques have been used in atrophic ridges to attain appropriate bone volume and enable dental implant insertion. By reducing the need for autogenous bone and decreasing morbidity at the donor sites, the use of bone substitutes has improved patient comfort and satisfaction. One of the major challenges in implant dentistry is achieving an optimal esthetic result with implant-supported crowns in the esthetic zone. Multiple prosthetic and surgical aspects need to be carefully planned and executed to achieve the final esthetic result...

AIM: To investigate the efficacy of alveolar ridge preservation (ARP) in periodontally compromised molar extraction sites. METHODS: An electronic search was performed on 10th November 2023 across five databases, seeking randomised/non-randomised controlled trials (RCTs/NCTs) that included a minimum follow-up duration of four months. The RoB2 and Robins-I tools assessed the risk of bias for the included studies. Data on alveolar ridge dimensional and volumetric changes, keratinized mucosal width, and need for additional bone augmentation for implant placement were collected...

OBJECTIVE: This study was designed to estimate the effect of sticky bone combined with concentrated growth factor (CGF) on anterior alveolar horizontal augmentation during implantation. METHODS: Twenty-eight patients were randomly assigned to either the test group (Group 1, n = 14) or the control group (Group 2, n = 14). Patients in Group 1 and Group 2 underwent GBR using sticky bone combined with CGF and bone powders mixed with saline, respectively...

BACKGROUND: Guided Bone Regeneration (GBR) is a versatile technique employed not only to correct pre-implant alveolar bone defects but also to facilitate bone defect correction during simultaneous implant placement. The effectiveness of GBR varies significantly among different protocols, as reported in the literature. This study specifically aimed to radiologically evaluate the horizontal bone gain obtained using a GBR procedure combining a particulate allograft, platelet-rich fibrin, resorbable collagen membrane, and screw tents...

Endosseous implants have revolutionized the field of Implants and Prosthodontics. Implant placement is a viable option in the treatment of partial and full edentulism. However, placement of implants in alveolar deficiencies may lead to adverse angulations, mechanical overload and esthetic dissatisfaction. When minimum dimensions for implant placement are not present in alveolar process, it is necessary to augment the size of the ridge. This can be achieved by various methods and materials. Here in this article presented a successful case of a 27 year old male patient with horizontal ridge augmentation in anterior left central incisor region using autogenous chin graft followed by the placement of implants after a period of six months of grafting and finally the prosthesis given after a period of six months of healing of implants...

This case report provides a detailed description of a simple and fast bone regeneration procedure using a semi-customized three-dimensional ultra-fine titanium mesh. A 50-year-old male with a severe vertical and horizontal bone defect in the anterior mandible underwent implant treatment in a staged approach. The autologous bone was combined with a xenograft, and the mixture was grafted to augment the bone defect and covered with semi-customized ultra-fine titanium meshes, which were selected among its various types according to size and configuration of the bone defect, directly connected and immobilized on the tenting screws with minimal shaping...

After dental extraction a physiological phenomenon of reabsorption of the dentoalveolar process is triggered, especially if periradicular lesions are present, which can sometimes be associated with oro-antral communication in the upper posterior maxilla. With the aim of proposing a minimally invasive approach, 19 patients undergoing tooth extraction in the postero-superior maxilla were recruited. All cases presented an oroantral communication with a diameter of 2-5 mm after tooth extraction and the alveolar process, in some cases, with a partial defect of one or more bony walls...

BACKGROUND: Gingival recession (GR) in malposed tooth in association with bone dehiscence and/or fenestration poses a challenge for successful root coverage treatment. Lateral closed tunnel (LCT) technique is particularly useful in isolated GR in mandibular anterior region, where the shallow vestibular depth prevents tension-free coronal mobilization of tissues. METHODS: Twenty patients with GR associated with tooth malposition were treated using a combined orthodontic-periodontic approach with a torquing auxiliary spring followed by LCT technique...

AIM: This study aimed to compare the efficacy of autogenous onlay and inlay grafts for anterior maxillary horizontal ridge augmentation. MATERIALS AND METHODS: This randomized clinical trial was performed on 14 patients with a deficient partially edentulous anterior maxillary ridge (3-5 mm in width). Patients were randomized and grouped into two equal groups: Group A was treated with symphyseal autogenous bone block, which was placed and fixed buccally as an onlay graft, and group B: was treated with symphyseal autogenous bone block, which was interpositioned and fixed in space created between buccal and lingual cortex as inlay graft...

Tooth loss often leads to significant alveolar bone resorption, presenting a challenge for dental implant placement. This case report presents the effectiveness of concentrated platelet-rich fibrin (C-PRF) in combination with bone allograft for horizontal bone augmentation in a severely atrophic maxilla. A 33-year-old female patient with extensive bone loss in the upper anterior maxilla was treated in two stages. The initial stage involved horizontal bone augmentation using a mixture of C-PRF and bone allograft...

OBJECTIVES: This case series aimed to assess the efficacy of a novel horizontal ridge augmentation modality using histology. Combinations of "sticky bone" and tenting screws without autologous bone were used as augmentative materials. METHODS AND MATERIALS: Five individuals presenting healed, atrophic, partially edentulous sites that required horizontal bone augmentation before implant placement were enrolled. Patients underwent the same augmentation type and five months of postoperative reentry procedures...

BACKGROUND: Current evidence acknowledges guided bone regeneration (GBR) as a predictable therapeutic modality in the augmentation of a deficient alveolar ridge. Such deficiencies often reveal inadequate bone volume to support implant placement in a position amenable to prosthetic reconstruction. Additionally, an evolving body of literature demonstrates that membrane fixation may lead to improved clinical bone gain through positively influencing blood clot formation, stability, and the eventual osteogenic potential of the defect...

OBJECTIVES: To introduce a modified guided bone regeneration (GBR) technique using intact periosteum and deproteinized bovine bone mineral (DBBM) for peri-implant augmentation and compare the clinical outcomes with those of conventional GBR. MATERIALS AND METHODS: Patients who received peri-implant augmentation in posterior sites between 2015 and 2021 were reviewed in this study. Group A was treated with a modified GBR technique, and Group B was treated with conventional GBR...

BACKGROUND: Dental implantology's success relies on adequate bone volume and quality, necessitating bone augmentation for implant placement. Primary lateral bone augmentation, utilizing autogenous block grafts, addresses horizontal bone loss. OBJECTIVE: This study aims to evaluate the efficacy of autogenous block grafting, specifically ramus and fibula blocks, in addressing severe atrophic ridges before and after implant placement. METHODS: Twenty-one patients underwent block grafting, predominantly using the ramus technique (80/20 ratio)...

INTRODUCTION: Although various surgical techniques have been utilized in the reconstruction of severely resorbed alveolar bone, its regeneration is still regarded as a major challenge. Most of the surgical techniques used in advanced ridge augmentation have the disadvantages of prolonging the patient's edentulous healing and increasing the need for surgical revisits because simultaneous implant placement is not allowed. This report presents a new and simplified method for advanced ridge augmentation, which utilizes a vertical tenting device...

Idiopathic osteosclerosis (IO) are focal radiopacities of unknown etiology observed in the jaws. These radiopacities are incidentally detected on dental panoramic radiographs taken for other reasons. In this study, we investigated the performance of a deep learning model in detecting IO using a small dataset of dental panoramic radiographs with varying contrasts and features. Two radiologists collected 175 IO-diagnosed dental panoramic radiographs from the dental school database. The dataset size is limited due to the rarity of IO, with its incidence in the Turkish population reported as 2...

This exploratory case series clinically and histologically investigated the performance of allogeneic cancellous freeze-dried bone allograft (FDBA) bone blocks (Maxgraft® ) for the lateral augmentation of local alveolar defects in the posterior maxilla as part of two-staged implant therapy. Five patients receiving eight implants 5 months after block augmentation with a follow-up period of up to 3 years were documented and analyzed. Horizontal alveolar dimensions before and 5 months after block augmentation were quantified using CBCT...
