Introduction In the posterior maxillary sextants, insertion of implants of desired length and diameter is often limited by the dimensional alterations of the residual ridge as well as the pneumatization of the maxillary sinus occurring after tooth loss. Transcrestal sinus floor elevation (tSFE) represents a surgical option to vertically enhance the available bone in the posterior maxillary sext...

The aim of this study is to evaluate the efficacy of the application of allogenous bone at the maxillomandibular reconstructions for future rehabilitation with dental implants. The patients were submitted to reconstruction of maxilla, using allogeneic bone grafts, in 3 different techniques: onlay grafts for lateral ridge augmentation, onlay and particulate bone for sinus lift grafting, and part...

OBJECTIVE This study aims to evaluate the usefulness of the CompuDent program in determining the pre-operative volume of bone graft in maxillary sinus floor lifts, and to calculate the volume of graft necessary for rehabilitation using varying lengths of implants. STUDY DESIGN Based on the CompuDent program, we calculated the volume of graft necessary for 47 sinus lifts. This volume was measu...

The aim of this case report is to present a case of root fragment removal during planned sinus lift procedure. After failed molar tooth extraction, we chose to retrieve the residual root apex with transantral approach not to damage excessively bone volume. Without changing primary implant rehabilitation purpose, the fragment removal procedure was performed prior to implant placement during nece...

A technique is described for accomplishing both localized sinus augmentation and guided bone regeneration at the time of maxillary molar extraction. One hundred nine sites were treated in 92 patients. Of these, 102 procedures (94.0%) were successful and 7 (6.0%) were partially successful. Success was defined as the ability to ideally position an implant at least 10 mm in length and 4.8 mm in wi...

PURPOSE To evaluate the regenerative potential of a fully synthesized homogenous hydroxyapatite:β-tricalcium phosphate 60:40 alloplast material in sinus lift procedures. MATERIALS AND METHODS Hydroxyapatite:β-tricalcium phosphate was used for sinus floor augmentation. After 9 months, 12 biopsies were taken from 12 patients. Routine histologic processing was performed and specimens were analyz...

Objectives/Hypothesis: To present a novel technique based on the combination of aesthetic and reconstructive techniques for the radical and safe excision of preauricular sinus along with minimal cosmetic impairing. Study Design: Case report, description of surgical method and brief overview of the literature. Methods: In a patient with bilateral preauricular sinus, we used a modified face-lift ...

Sinus augmentation is a well-known approach to treating alveolar bone ridge atrophy in the posterior maxilla. The preparation of the lateral window is crucial. Its size, design, and position in the vestibular sinus wall may affect the intra- and postsurgical complication rates and affect the intrasurgical activity of both surgeons and assistants. The present paper describes a rational technique...
