Surgical management of the buccal bifurcation cyst: bone grafting as a treatment adjunct to enucleation and curettage.

The buccal bifurcation cyst (BBC) is a rare inflammatory odontogenic cyst of unknown etiology. It typically develops on the buccal aspect of the permanent mandibular first molar and occasionally on the permanent mandibular second molar in children 4 to 14 years old. Distinct clinical findings of the BBC include involvement of a vital partially or fully erupted mandibular first or second molar, swelling in the affected mandibular molar region, delayed or altered eruption pattern of the involved tooth, and an increase in periodontal pocket depth when the affected tooth is partially erupted.

Correlation between Schneiderian membrane perforation and sinus lift graft outcome: a retrospective evaluation of 359 augmented sinus.

Augmentation of the anterior maxilla with intraoral onlay grafts for implant placement.

The use of autogenous cortical cancellous block grafts to augment the premaxilla is a safe and effective technique to provide adequate bone height and width when reconstructing patients with atrophic premaxilla ridge when endosteal implants are planned. Intraoral bone graft harvests have the advantages of proximity of the donor site to the graft site, convenient surgical access, minimal operative time, and ease of performance in an office setting. The major limitation of these donor sites is the smaller quantity of graft obtainable compared with iliac crest bone harvest sites.

Effect of sinus membrane perforation on dental implant integration: a retrospective study on 128 patients.

Off-label use of rhBMP-2 for reconstruction of critical-sized mandibular defects.

Techniques for reconstructing segmental defects of the mandible have traditionally relied upon autogenous tissue transfer. Tissue engineering has brought about the promise of de novo bone formation and the possibility of reconstruction of these defects without the drawbacks of traditional techniques. Bone morphogenic proteins (BMP) have presented themselves as the most promising in this field.

Use of tilted implants in treatment of the atrophic posterior mandible: a preliminary report of a novel approach.

Purpose: Restoration of the atrophic partially edentulous posterior mandible with implant retained prostheses has proved to be problematic, with no ideal treatment modality. The purpose of this report is to offer a novel method of treatment using tilted endosseous implants.

Materials And Methods: A total of 64 patients with edentulous spans of the mandible and less than 9.

Root and pulp response after intentional injury from miniscrew placement.

Introduction: The purpose of this study was to evaluate the effects on the pulp and supporting tissues when miniscrews severely abrade the root surface.

Methods: Sixty self-drilling and self-tapping miniscrews were placed between the premolars and molars of 3 beagles (20 miniscrews per dog). The miniscrews were placed according to the protocol suggested by the manufacturer, but with the intention of inflicting root damage.

Cementum, pulp, periodontal ligament, and bone response after direct injury with orthodontic anchorage screws: a histomorphologic study in an animal model.

Purpose: To assess the histologic response of the periodontium, cementum, and pulp after intentional root injury with titanium screws.

Materials And Methods: Three female beagle dogs were used, and a total of 60 self-drilling/self-tapping miniscrews were manually inserted into the maxilla and the mandible with the intention of placement in close proximity or in direct contact with the roots. Digital radiographs were taken to select the sites with root injuries.

Outcomes of placing short dental implants in the posterior mandible: a retrospective study of 124 cases.

Bisphosphonate use and health history questionnaire.

The health history form is a rapid, time-honored method used by practitioners to assess a patient's medical history before treatment. Because of increased reports of bisphosphonate-related osteonecrosis of the jaws (BRONJ), we investigated the percentage of our patients taking oral bisphosphonates who actually reported taking the medication on our health history form. A questionnaire inquiring about bisphosphonate use was sent to 1,400 female patients who had undergone implant placement in the last five years.

Outcomes of placing dental implants in patients taking oral bisphosphonates: a review of 115 cases.

Purpose: In recent years, numerous cases of bisphosphonate-associated osteonecrosis of the jaw have been reported involving both intravenous and oral therapy regimens. The majority of these cases have involved intravenous bisphosphonates. Subsequently, drug manufacturers and the US Food and Drug Administration issued warnings about possible bisphosphonate-associated osteonecrosis of the jaw.

Management of patients with trigeminal nerve injuries after mandibular implant placement.

Background: Placement of mandibular endosseous implants can result in damage to the lingual nerve, the inferior alveolar nerve or both nerves. All dentists who place mandibular implants should be aware of the appropriate early management of these injuries, as well as the appropriate time to refer patients with these injuries to a microneurosurgeon.

Overview: The lingual nerve is less likely to undergo spontaneous regeneration than is the inferior alveolar nerve, which is protected within the inferior alveolar canal.
