Clinical and Histological Assessment of Hybrid Bone Regeneration (HBR®) Surrounding Dental Implants.

Description :

Description of study population All patients needing implant therapy for fixed prosthetic rehabilitation were eligible for entering this study, provided that they fulfilled the following inclusion criteria: i) Width of the residual bone crest in the programmed implant site between 2 and 5 mm. ii) Healed bone crest (almost three months elapsed after extraction or tooth loss). iii) Patient age > 18 years. iv) Patients able to examine and understand the study protocol. The following exclusion criteria were adopted: i) Myocardial infarction within the past 6 months. ii) Poorly controlled diabetes (HBA1c > 7.5%). iii) Coagulation disorders. iv) Radiotherapy to the head/neck district within the past 2 years. v) Present or past treatment with intravenous bisphosphonates. vi) Immunocompromised patients. vii) Psychological or psychiatric problems. viii) Alcohol or drugs abuse. ix) Poor oral hygiene and motivation (full mouth plaque score >30% and/or full mouth bleeding score >20%). x) Uncontrolled periodontal disease. Population Characteristics: Patients presenting to the Department of Oral Surgery at Saint Joseph University of Beirut for dental treatment with the above-mentioned exclusion and inclusion criteria. Population Size: The clinical trial will include 30 patients that require dental implants in partially edentulous sites with a need for lateral guided bone regeneration. GBR and implants will be placed at the Oral Surgery Department of the Faculty of Dental Medicine of Saint Joseph University of Beirut, and the restorative crowns will be done at the Prosthodontics Department of the Faculty of Dental Medicine of Saint Joseph University of Beirut.
