The aim of this work was to test the effectiveness of using enzymatically deantigenated equine bone block as a scaffold for guided bone regeneration (GBR) during a horizontal augmentation of the lower jaw. A partially edentulous atrophic mandible was augmented using an equine-derived block with an expanded polytetrafluoroethylene membrane. After 8.5 months, two bone core samples were collected at the augmentation site, and implants were placed. A definitive prosthesis delivered 6 months after implant placement provided excellent functional and aesthetic rehabilitation throughout the follow-up period. Histological and histomorphometrical analysis of the biopsies showed newly formed bone to be present and the residual biomaterial was still undergoing remodeling. Comparison of cone beam computed tomography scans taken before augmentation and 26 months later showed maintenance of ridge width and possible corticalization of the vestibular augmented ridge side. The equine-derived bone block placed in accordance with GBR principles provided a successful clinical, radiographic, and histological outcome.

Abstract Insufficient width of the alveolar ridge often prevents ideal implant placement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentation of the alveolar ridge. Ridge splitting is a minimally invasive technique indicated for alveolar ridges with adequate height, which enables immediate implant placement and eliminates morbidity and overall treatment time. The classical approach of the technique involves splitting the alveolar ridge into 2 parts with use of ostetomes and chisels. Modifications of this technique include the use of rotating instrument, screw spreaders, horizontal spreaders and ultrasonic device. The purpose of this article is to thoroughly describe all the different approaches in ridge splitting technique. 2 interesting clinical cases of narrow alveolar ridges treated with ridge splitting and immediate implant placement are also presented.

The extraction of teeth results in rapid bone resorption both vertically and horizontally in the first month. The loss of alveolar ridge reduces the chance of implant rehabilitation. Atraumatic extraction, implant placement in extraction socket, and an immediate prosthesis have been proposed as alternative therapies to maintain the volume and contours tissue and reduce time and cost of treatment. The immediate load of implants is a universally practiced procedure; nevertheless a successful procedure requires expertise in both the clinical and the reconstructive stages using a solid implant system. Excellent primary stability and high bone-implant contact are only minimal requirements for any type of implant procedure. In this paper we present a case report using a new type of implants. The new type of implants, due to its sophisticated control system of production, provides to the implantologist a safe and reliable implant, with a macromorphology designed to ensure a close contact with the surrounding bone.

Orthodontic Extrusion

Implant placement is often necessitated for replacement of teeth with pathologically damaged alveolar bone due to periodontitis or traumatic injury. Surgical augmentation of resorbed bone has many limitations, including lower efficacy of vertical augmentation than horizontal augmentation, as well as morbidity associated with grafting procedure. Orthodontic therapy has been proposed as a useful method for augmenting the resorbed alveolar bone and reforming aesthetically appealing gingival margin, prior to implant placement. This narrative review summarizes the available evidence for the application of orthodontic strategies that can be used as adjunct in selected cases to augment bone volume for the future implant site and maintain space for the prosthetic parts of the implant. These are (1) orthodontic extrusion of compromised teeth to generate vertical bone volume and enhance gingival architecture, (2) tooth preservation and postponing orthodontic space opening to maintain bone volume in future implant site, (3) orthodontic implant site switching to eliminate the deficient bone volume or risky implant sites, and (4) the provision of a rigid fixed-bonded retainer to maintain the implant site. Although there are no randomized controlled clinical trials to evaluate the efficacy of orthodontic therapy for implant site development, clinical case reports and experience document the efficacy of orthodontic therapy for this application.

Abstract This clinical review is an evaluation of the effectiveness of the split ridge bone augmentation technique performed in the atrophic maxilla and mandible with buccolingual bony defects. The osseointegration success of implant placement in the area of split ridge bone augmentation is assessed and compared to implant success rates indicated in the literature. This evaluation includes 15 patients who were treated with alveolar split ridge bone augmentation at Tufts University School of Dental Medicine. During initial consultation, all patients were diagnosed with a buccolingual bone dimension of 3–5 mm on the edentulous alveolar crest. This bony buccolingual dimension was inadequate for placement of implants of desirable width and correct angulation as dictated by the prosthetic requirements. Crestal split augmentation technique involved a surgical osteotomy that was followed by alveolar crest split and augmentation after buccolingual bony plate expansion, prior to implantation. Implants were placed either immediately or 3 weeks after the initial augmentation. No fixation was used to stabilize the buccal bony cortex after the completion of the augmentation. All patients were placed on periodic follow-ups for a 24-month period postoperatively. Implant success was determined with the use of Buser's Criteria. In total, 33 implants were placed in 15 patients. The overall success rate of osseointegration of the endosseous implants placed in the area of split ridge bone augmentation was found to be 97%. One patient presented with facial bone resorption and implant mobility 4 months after the surgery. The implant was removed and the area was reconstructed with autogenous bone graft and later implanted with an endosseous implant. Our results indicate that the split crest bone augmentation technique is a valid reconstructive procedure that can be used to augment the buccolingual alveolar defect prior to implant placement providing good bone foundation for placement of implants with desirable width in favorable angulation. In comparison to traditional bone grafts techniques, crestal split ridge bone augmentation enables placement of dental implants immediately or 3 weeks after augmentation and eradicates the possible morbidity of the donor sites.

Abstract Few studies have examined the biomechanical effects of dental implant placement in the implant-supported mandibular advancement device (MAD) for the treatment of obstructive sleep apnea in completely edentulous patients. This biomechanical study aimed to evaluate the stability of the implant-supported MAD for different numbers and positions of dental implants. A 3D edentulous maxillofacial model with the one-piece MAD was considered for various numbers and positions of implants. On each mandible and maxilla, one, two, four, or six implants were placed symmetrically in various positions. Total 42 implant placements were considered. A static finite element analysis was performed under the mandibular posterior restorative force for 40% protrusion. The maximum and minimum principal stresses on the cortical and cancellous bones and the von Mises stresses on the implant were measured. When four implants were placed on each maxilla and mandible, the maximum average stress on the cancellous bone was reduced by up to approximately three times compared with the cases of placing two implants on each maxilla and mandible. The placement of at least four implants on each maxilla and mandible improved MAD stability. It is noteworthy that the mandibular implants should be arranged adjacently to avoid stress concentration in the second molar.

Abstract This clinical report describes the oral rehabilitation of a 15-year-old male patient who was involved in a snowmobile accident and suffered multiple mid-face and mandibular fractures. Consequences of the accident included avulsion of teeth numbers 5 to 10 and 21 to 26, and a significant amount of maxillary and mandibular anterior alveolar bone loss. The patient underwent open reduction and rigid fixation of the fractured left zygoma, comminuted LeFort I maxillary fracture, and left body of the mandible; closed reduction of the bilateral condylar fractures; autologous corticocancellous bone grafting to the maxilla and mandible; implant placement; and prosthesis fabrication. This multidisciplinary approach successfully restored function and esthetics.

Horizontal lack of residual ridge width can complicate the implant procedures. Therefore, ridge construction prior to implant placement is a biomechanical requirement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentation of the alveolar ridge. The ridge splitting technique with simultaneous implant placement seems to be a minimally invasive treatment option for horizontal augmentation of narrow alveolar ridges with adequate vertical height. This paper thoroughly describes a segmental ridge splitting technique with both vertical and horizontal osteotomy cuts followed by the use of chisel and mallet to lateralise the buccal bone which was accompanied by GBR and simultaneous implant placement.
