Maxillary sinus lift augmentation: A randomized clinical trial with histological data comparing deproteinized bovine bone grafting vs graftless procedure with a 5-12-year follow-up.

Introduction: Different protocols and procedures for sinus lift and implant placement are available, generally involving the use of grafts to increase the tissue volume and/or prevent the Schneiderian membrane from collapsing. Among xenografts, deproteinised bovine bone graft (DBBP) is frequently used in sinus lift procedures. Leaving an ungrafted space following membrane elevation has proven to have a bony regenerative potential as well.

Mucoceles of the oral cavity: a large case series (1994-2008) and a literature review.

Objectives: Evaluating data of patients affected by oral mucoceles, examined at the Unit of Oral Medicine and Pathology of the University of Milan between January 1994 and December 2008.

Study Design: Concise review on oral mucoceles and analysis of the clinical files of patients who underwent excisional biopsy (patient age, medical history, diagnosis, date and site of the biopsy, histopathological diagnosis and recurrences if any).

Results: During the period June 1994-December 2008, 158 mucoceles were observed (93 males and 65 females), with the most frequent site being the lower lip (53%) (p=0.

Immediate/early function with tapered implants supporting maxillary and mandibular posterior fixed partial dentures: preliminary results of a prospective multicenter study.

Statement Of Problem: While immediate loading in the interforaminal area of the mandible is a documented procedure, there are limited scientific data for immediate/early loading in premolar and molar areas where less bone density is often found and functional loading is high.

Purpose: The purpose of this study was to evaluate if there is a difference between immediate and early loading in premolar and molar areas of the mandible and maxilla and compare data to historic data.

Material And Methods: Fifty-one patients received 120 tapered implants in premolar and molar areas of the mandible and maxilla, for a total of 54 short-span (2 to 4 units) fixed partial dentures.
