Prevalence of complications after the oral rehabilitation with implant-supported hybrid prostheses
2010
Objectives: Assess the main problems referred by the patients and observed by the professionals after the bucodental rehabilitation with an implant-supported hybrid prothesis. Patient and Methods: A retrospective study was carried out in which there were 43 patients included who were visited in the Department of Oral Surgery and Orofacial Implantology of University of Barcelona Dental School for one year. An oral rehabilitation with an implant-supported hybrid prosthesis was made to those patients. The following variables were registered: age, gender, number of inserted implants, type of implant and principal problems produced by the hybrid prosthesis. Results: The rehabilitation with an im…
Placement of endosseous implants in patients with oral epidermolysis bullosa.
2000
Abstract Objective: To evaluate the feasibility of placing endosseous implants in patients with recessive dystrophic epidermolysis bullosa. This article reports on 4 patients subjected to follow-up. Study Design: Implants were placed in 4 cases. All patients have marked oral involvement, with devastating alterations in the soft and hard tissues in all cases. Results: A total of 15 implants (7 maxillary, 8 mandibular) were placed. All implants integrated successfully and have been restored. The average follow-up from implant placement was 2.5 years (range, 1-4). Conclusions: Our preliminary findings suggest that endosseous implants can be successfully placed and can provide support for prost…
Survival and tissue maintenance of an implant with a sloped configurated shoulder in the posterior mandible-a prospective multicenter study.
2016
Aim Clinical studies evaluating the influence of the implant design on the preservation of peri-implant keratinized mucosa are rare. The aim of this prospective multicenter study was to investigate the survival, and soft and hard tissue maintenance of an implant with a sloped shoulder configuration, when placed in the posterior mandible. Material and Methods In this study, 24 centers participated and 184 patients receiving 238 implants (OsseoSpeed™ Profile TX implants) were included. Clinical assessments of soft tissue parameters were performed before implant placement, immediately after implant placement, at prosthetic delivery and at 6, 12 and 24 months after implant placement and margina…
Clinical significance of interleukin-1 genotype in smoking patients as a predictor of peri-implantitis: A case-control study
2015
Background: Interleukin-1 (IL-1) is a proinflammatory cytokine that plays an important role in the pathogenesis of periodontitis, and so it might be useful to detect high-risk cases of peri-implantitis. It has been reported that IL-1 polymorphisms and smoking habit have a synergic effect, increasing the incidence of peri-implantitis. The aim of the present study was to evaluate the relationship between IL-1 gene polymorphisms and peri-implantitis in smoking patients. Material and Methods: A case-control study was performed in 27 patients with peri-implantitis and 27 patients with healthy implants. All patients included were smokers. IL-1A-C889T, IL-1B+C3953T and IL-1RN+T2018C were identifie…
Use of buccal fat pad to repair post-extraction peri-implant bone defects in the posterior maxilla: a preliminary prospective study
2015
Background: Extensive literature exists about the use of the BFP in the treatment of oral defects but, to our knowledge, no article refers to the use of the BFP as a substitute of the membrane barriers for treatment of peri- implant bone defects. The aim was to evaluate the use of the buccal fat pad as a coating material for bone grafting in the peri-implant bone defect regeneration of immediate implants placed in the posterior maxilla. Material and Methods: A preliminary prospective study of patients involving immediate implants in which the buccal fat pad was used as a coating material to peri-implant bone defects was carried out. The outcome measures assessed were: postoperative pain and…
Are mucous retention cysts and pseudocysts in the maxillary sinus a risk factor for dental implants? A systematic review
2020
Background Mucous retention cysts and pseudocysts of the maxillary sinus are benign lesions present in up to 13% of adult patients. Different surgical approaches for sinus lift and dental implant placement in the presence of these lesions have been proposed. Material and Methods A systematic review was performed following the PRISMA statement recommendations to answer the PICO question: Does the aspiration or removal of mucous retention cysts/pseudocysts before or during sinus lifting and dental implant placing, affect the survival of the implants? The study was pre-registered in PROSPERO (CRD42020185528). Included articles quality was assessed using the “NIH quality assessment tool” and “T…
Inflammatory implant periapical lesion: etiology, diagnosis, and treatment--presentation of 7 cases.
2008
Purpose To investigate implant periapical lesions, and to describe their treatment. The hypothesis of this evaluation is that implant periapical lesions are disorders of the area surrounding the apex of a dental implant, and that their etiology can be multifactorial (ie, vascular impairment, vascular ischemia, overheating of bone during drilling, and implant surface contamination). The diagnosis is based on the clinical manifestations and x-ray findings. The x-ray findings usually involve a periapical radiotransparency. Materials and Methods Seven patients with implant periapical lesions (3 in the upper jaw, and 4 in the mandible) after implant placement are described. All patients reported…
Relationship between preoperative anxiety and postoperative satisfaction in dental implant surgery with intravenous conscious sedation
2008
Purpose: To study if patient preoperative anxiety is related to age and gender and to compare preoperative anxiety with postoperative patient and surgeon satisfaction in dental implant surgery under intravenous conscious sedation. Materials and Methods: Dental implants were placed in 102 patients under local anesthesia and intravenous conscious sedation. The procedures were performed with or without dental extractions, and with or without bone regeneration. Anxiety was evaluated using Corah?s Dental Anxiety Scale and levels of surgeon and patient satisfaction were evaluated on an adapted scale. Results: Low preoperative anxiety was observed in 27.8% of patients, moderate in 50%, and high in…
Transcrestal sinus lift and implant placement using the sinus balloon technique
2011
Objective: A description is made of transcrestal sinus lift using the sinus balloon technique, evaluating the bone height achieved and implant success one year after prosthetic loading. Material and method: Between January and July 2007, transcrestal sinus lift using the sinus balloon technique for dental implant placement was carried out in 6 patients. A panoramic X-ray study and maxillary computed tomography scan were carried out before the operation, in order to discard possible sinus pathology. During the intervention, the integrity of the sinus membrane was evaluated using a Medi Pack Pal endoscope (Farol Store and Co., Tuttlingen, Germany), and the intraoperative complications were an…
Nanocrystalline Hydroxyapatite-Based Material Already Contributes to Implant Stability After 3 Months: A Clinical and Radiologic 3-Year Follow-up Inv…
2014
The present study reports on a 3-year clinical and radiologic follow-up investigation of dental implants placed 3 and 6 months after sinus augmentation in 14 patients. Augmentation was performed with a synthetic bone substitute material composed of nanocrystalline hydroxyapatite. The aim of the study was to determine how the integration period of the bone substitute material, that is, 3 months or 6 months, influences implant integration within the patient's upper jaw. Therefore, the following clinical and radiologic parameters were investigated: implant being in situ; Periotest value; and presence of peri-implant osteolysis, bleeding on probing, plaque, and soft tissue recession around the …
