Full arch immediate occlusal loading using site specific implants: A clinical series of 10 patients (13 arches).

PURPOSE: Osseointegration of dental endosseous implants has proven to be effective, predictable, and clinically successful. Unloaded healing protocols were originally used in treating edentulous patients. Full arch immediate occlusal loading protocols have been shown to be as effective as unloaded healing protocols. This paper reports on the results, benefits, and limitations of one specific immediate loading protocol using site specific implants for fresh extraction and healed extraction sites. MATERIALS AND METHODS: Ten consecutive patients [{13 arches} (age range: 64-81 years; average: 70.1) (4 males/6 females) were treated by the first 2 authors in private practice settings. Hopeless teeth were scheduled for extraction with immediate implant placement and immediate loading with insertion of full arch, screw-retained, acrylic resin interim prostheses within 24 hours. Implants were also placed into healed edentulous ridges. Insertion torque values for each implant were recorded. Interim prostheses were removed after at least 3 months of healing. Implants were reverse torque tested (35 Ncm) and evaluated for macroscopic mobility. Definitive full arch prostheses were made. Patients were followed for 21 to 48 months postimplant surgery. Panoramic radiographs were taken immediately postimplant placement and 1 year postoperative. RESULTS: Thirteen arches were treated; 11 ultrawide diameter implants were placed into molar sockets, 26 inverted body-shift implants were placed into anterior sockets; 25 standard diameter, tapered implants were placed into edentulous sites; 2 zygomatic implants were placed in one patient. The total number of implants placed was 64 (4 preexisting implants were also used and not included in this study). The minimum implant insertion torque value was 20 Ncm. After 12 to 18 months of function (average 14 months), the implant and prosthetic survival rates were 100%. Eight patients were restored with definitive zirconia or acrylic resin hybrid fixed prostheses. Two patients were restored with bar titanium frameworks and removable overdenture prostheses. No prosthetic complications were reported for the definitive prostheses. CONCLUSIONS: The results of this clinical series with site specific implants and immediate full arch occlusal loading in treating edentulous patients resulted in 100% clinical implant and prosthetic survival rates. According to this study, this protocol can be used with high levels of anticipated success.

Displacement of the Inferior Alveolar Bundle Secondary to Post Coronectomy Root Migration: A Case Report.

Intentional coronectomy has become a commonplace procedure as an alternative to full third molar removal in order to decrease the occurrence of inferior alveolar nerve (IAN) injury. It is well known that one of the sequelae of this procedure is superior root migration. This is usually not a significant problem as the migrated roots may erupt to a position where they are more readily removed. This report presents a case in which a curvature at the apex of the root displaced the IAN causing neurologic symptoms.

Implant-related nerve injuries.

Injuries to branches of the trigeminal nerves are a known complication during dental implant placement. These injuries tend to be more severe than those experienced during other dentoalveolar procedures. This article reviews the types of nerve injuries and areas and situations of which clinicians should be cognizant when placing dental implants. Strategies to avoid injuries, and a management algorithm for suspected nerve injuries, are also discussed.

Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures.

The Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures evidence-based clinical practice guideline was codeveloped by the American Academy of Orthopaedic Surgeons (AAOS) and the American Dental Association. This guideline replaces the previous AAOS Information Statement, "Antibiotic Prophylaxis in Bacteremia in Patients With Joint Replacement," published in 2009. Based on the best current evidence and a systematic review of published studies, three recommendations have been created to guide clinical practice in the prevention of orthopaedic implant infections in patients undergoing dental procedures. The first recommendation is graded as Limited; this recommendation proposes that the practitioner consider changing the long-standing practice of routinely prescribing prophylactic antibiotic for patients with orthopaedic implants who undergo dental procedures. The second, graded as Inconclusive, addresses the use of oral topical antimicrobials in the prevention of periprosthetic joint infections. The third recommendation, a Consensus statement, addresses the maintenance of good oral hygiene.

Timing of trigeminal nerve microsurgery: a review of the literature.

Injury to peripheral branches of the trigeminal nerve is a known sequelae of oral and maxillofacial surgery procedures. The most often studied and reported branches have been the inferior alveolar and lingual nerves. Many questions still remain unanswered concerning the appropriate timing of surgical repair. The literature frequently mentions specific timing guidelines, however, there is scant scientific evidence to support these guidelines. In fact, several authors of clinical series state that although many of their surgical procedures occurred fairly late due to the timing of referral and other issues such as insurance authorization, reasonable clinical results were still achieved in these patients. Various systems of nerve injury evaluation and testing methods make it difficult to draw specific timing recommendations. The consensus of literature reviewed indicates that more research is necessary in this area to better answer these questions.

Perioperative considerations in the management of pediatric surgical patients.

Pediatric anatomy and physiology differ significantly from those of adults and, therefore, require special considerations in evaluation and perioperative management. This article highlights the anatomic and physiologic differences that influence pediatric management. It also covers specific disease processes that are common in the pediatric population and that may involve special management strategies.

Management of parotid duct injuries.

Injuries to the buccal region of the face can carry multiple complications due to the complex anatomy that lies within. The facial nerve and the parotid duct can be easily injured by sharp or penetrating trauma to the cheek. The purpose of this paper is to present the full spectrum of current treatment modalities available to manage these injuries. The anatomy of the parotid gland and duct are described, and surgical techniques and therapeutic alternatives for the immediate and delayed treatment of the parotid duct injuries are reviewed. Clinical cases are presented to illustrate the treatment options outlined.

Odontogenic myxoma of the maxilla: a report of two pediatric cases.

Myxomas are benign, slow growing neoplasms derived from mesenchyme. While these tumors most frequently occur in the myocardium, the other sites most commonly affected are the maxilla and mandible. Nevertheless, myxoma is a very uncommon lesion of the midface, particularly in the pediatric population. We present two reports of infant children with midfacial myxomas. The clinical features, radiographic evaluation and treatment of these cases will be presented.
