RESUMEN
The rehabilitation of patients with failing or missing dentition using titanium implants has dramatically changed in the last decades. Despite the predictability of implant therapy, failures that mandate implant removal do occur. The aim of our study was to determine the failure rates of implants placed during the last nine years at the dental clinic of the Faculty of Dental Medicine at Saint-Joseph University, Beirut. 640 individuals received dental implants; failures were clustered in 75 [11.7%] patients [27 men and 48 women, mean age 49.66 +/- 13.4 years]. The total failure rate was 5.68%. Most failures were early [66.3%] and a statistically significant decrease in failure rate was observed during the last years [p=0.003]
RESUMEN
Since the 1960s, the introduction of osseointegration principles and improved surgical protocols has resulted in an increasing use of oral implants in clinical practice. Despite their high long-term success rates in the rehabilitation of fully or partially edentulous patients, dental implants failures might occur. The implant failure can be classified as early failure [the osseointegration is not yet established] and late failure [involving a breakdown of the established osseointegration]. The aim of this article was to present a literature review regarding mechanism, etiologies and risk factors associated with implant failures
RESUMEN
The periodontal abscess is a localized purulent infection that affects the tissues surrounding a periodontal pocket and causes the destruction of tooth supporting structures. Various etiologies have been proposed. The symptoms and the clinical aspect often guide the practitioner toward the diagnosis and treatment choices of this entity, particularly in its palatal location. This case report is interesting because of the uncommon associated signs and symptoms, the concomitance of other mucosal lesions, the management and therapeutic approach adopted and the follow up of the patient during the healing phase
