Transcrestal sinus lift and implant placement using the sinus balloon technique.

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.

Radiographic findings in the maxillary sinus: comparison of panoramic radiography with computed tomography.

Purpose: To assess the prevalence of radiographic signs of maxillary sinus pathology in patients undergoing dental implant treatment and to compare the efficacy of panoramic radiography, computed tomography (CT), and three-dimensional (3D) CT with Implametric software in the diagnosis of sinus pathology.

Materials And Methods: Thirty patients were selected at random from those being treatment-planned to receive implant-supported restorations in the maxilla and who had a panoramic radiograph, a conventional CT scan in acetate, and a 3D CT scan in digital format. The radiographic maxillary sinus findings were categorized as: (1) no sign of pathology, (2) mucosal thickening, (3) mucous cyst, or (4) occupation of the entire sinus.

Rehabilitation of atrophic posterior maxilla with zygomatic implants: review.

The objective of this study was to review the published literature to evaluate treatment success with zygomatic implants in patients with atrophic posterior maxilla. Studies from 1987 to 2010 were reviewed. In each study, the following were assessed: indications for treatment, number of patients, number of implants, length and diameter of the implants, surgical technique, prosthetic rehabilitation, success rate, complications, and patient satisfaction.

Prevalence, location, and size of maxillary sinus septa: panoramic radiograph versus computed tomography scan.

Purpose: To determine the prevalence, location, and size of maxillary sinus septa, and to compare the results of panoramic radiographs and computed tomography (CT) scans.

Materials And Methods: This study included 30 patients, 17 women and 13 men, with a mean age of 50.9 years (range, 28-73 years), undergoing treatment planning for implant-supported restorations in the maxilla.

Clinical characteristics, treatment, and evolution of 89 mucoceles in children.

Purpose: The present study was undertaken to evaluate mucoceles in the oral cavity of pediatric patients, including the clinical characteristics, treatment, and progress of the lesions.

Patients And Methods: A retrospective study was performed from the medical records of patients (0-14 years old) treated for oral mucoceles between 1998 and 2008 in a reference children's hospital. All subjects with mucoceles on lips, mouth, buccal mucosa, and palate were included.

Expression of cytokeratins in epithelialized periapical lesions.

Objective: This study attempted to clarify whether differential immunocytokeratin expression occurs in cystic and epithelialized noncystic lesions.

Study Design: From January 2003 to June 2004, periapical surgery was carried out on 70 teeth, collecting 70 histologic samples. Serial sections of original histologic slices were prepared for immunostaining.

Comparative study of wide-diameter implants placed after dental extraction and implants positioned in mature bone for molar replacement.

Objective: The aim of this study was to compare wide-diameter implants placed in mature bone versus implants inserted in postextraction bone.

Material And Methods: A retrospective case study was made; the sample was composed of subjects who had had wide implants placed in the molar area between 2003 and 2005. Two groups were formed: implants placed in mature bone and implants in postextraction bone.

Immediately restored dental implants for partial-arch applications. A literature update.

This article carries out a literature update on immediately restored dental implants in partially edentulous patients. A search was made in Medline of all articles published between the year 2000 and February 2007, including all articles published in both English and Spanish, in which immediate restoration of implants was made of partially edentulous areas with a minimum of 12 implants and six months follow-up. Certain decisive factors exist for the success of this technique in partially edentulous patients, such as primary stability, a roughened implant surface, and the absence of parafunctional habits in patients acceptable for this type of treatment.

Resonance frequency analysis of dental implant stability during the healing period.

Purpose: The objective of the present study was to measure the implant stability quotient (ISQ) values during the osseointegration period, and determine the factors that affect implant stability.

Materials And Methods: To measure implant stability, resonance frequency analysis (RFA) was performed in 24 patients (12 women, 12 men) with a total 64 Defcon implants (10 anterior maxilla, 12 posterior maxilla, 18 anterior mandible, 24 posterior mandible). Bone type was classified according to the Lekholm and Zarb index (52 type II bone, 12 type III).

The post-endodontic periapical lesion: histologic and etiopathogenic aspects.

Apical periodontitis is produced in the majority of cases by intraradicular infection. Treatment consists in the elimination of the infectious agents by endodontia. Even when carrying out a correct cleansing and filling of canals, it is possible that periapical periodontitis will persist in the form of an asymptomatic radiolucency, giving rise to the post-endodontic periapical lesion.
