Immediate Placement and Loading of Maxillary Single-Tooth Scalloped Implants and Digitally Customized Restorations: A 5-Year Prospective Study of Marginal Bone Level.

Purpose: To evaluate over 5 years the mesial, distal, palatal, and buccal bone levels as well as the buccal bone thickness surrounding scalloped implants that were immediately placed and loaded with provisional crowns fixed on final prefabricated abutments.

Materials And Methods: A total of 18 implants were placed and immediately loaded using CAD/CAM technology in 18 patients to replace a single tooth in the anterior maxilla. The marginal bone levels around the scalloped implant necks were measured mesially and distally using intraoral standardized radiographs after crown placement as well as at the 1-, 3-, and 5-year follow-ups.

Benign mesenchymal odontogenic tumors of the maxillofacial bones: A report of 3 cases with 3 years follow-up.

Benign mesenchymal odontogenic tumors are lesions derived from the mesenchymal components of the tooth-forming apparatus and are consequently found within the jawbone. Benign fibro-osseous tumors are part of this category of lesions in which normal bone is substituted, initially by fibrous tissue and within time become infiltrated by osteoid and cementoid elements. They are asymptomatic, slow-growing lesions and remain undiagnosed until swelling of the face becomes prominent and they share similar radiological characteristics.

Comparison of Bone Levels Around Immediately Loaded Single Implants Placed in Healed or Freshly Extracted Sites in the Esthetic Anterior Maxilla: A 10-Year Prospective Study.

Purpose: To evaluate retrospectively at 10 years the marginal bone levels around implants located in healed ridges or in extraction sockets and loaded immediately with provisional crowns fixed in prefabricated abutments.

Materials And Methods: Forty-two implants were placed in 36 patients needing single tooth replacement. Implants were inserted either in healed ridges (group 1) or in extraction sockets (group 2) and loaded immediately with prefabricated abutments.

Cyst volume changes measured with a 3D reconstruction after decompression of a mandibular dentigerous cyst with an impacted third molar.

The aim of this article is to describe a large mandibular cyst treated with decompression followed by surgical enucleation. Furthermore, we described the utility of cyst volume measurements by using a 3D reconstruction on Cone Beam Computed Tomography (CBCT). The dentigerous cyst is the most common cyst type of epithelial origin, arising from remnants of odontogenic epithelium, asymptomatic and associated with the crown of an unerupted or partially or completely impacted tooth.

Immediate placement and loading of maxillary single-tooth implants: a 3-year prospective study of marginal bone level.

Aim: The purpose of this study was to evaluate marginal bone level around single-tooth implants placed in anterior maxilla and immediately restored.

Materials And Methods: Twenty implants were placed in 20 patients (8 men and 12 women) that were selected for this study. Following atraumatic non-surgical extraction of tooth, all patients immediately received implants and the definitive prefabricated abutment was placed.

Influence of surgical and prosthetic techniques on marginal bone loss around titanium implants. Part I: immediate loading in fresh extraction sockets.

Purpose: Delayed placement of implant abutments has been associated with peri-implant marginal bone loss; however, long-term results obtained by modifying surgical and prosthetic techniques after implant placement are still lacking. This study aimed to evaluate the marginal bone loss around titanium implants placed in fresh extraction sockets using two loading protocols after a 5-year follow-up period.

Material And Methods: A total of 36 patients received 40 titanium implants (Astra Tech) intended for single-tooth replacement.

A 5-year comparison of marginal bone level following immediate loading of single-tooth implants placed in healed alveolar ridges and extraction sockets in the maxilla.

Purpose: The aim of present investigation was to evaluate marginal bone level after 5-year follow-up of implants placed in healed ridges and fresh extraction sockets in maxilla with immediate loading protocol.

Materials And Methods: Thirty-six patients in need of a single-tooth replacement in the anterior maxilla received 42 Astra Tech implants (Astra Tech Implant system™, Dentsply Implants, Mölndal, Sweden). Implants were placed either in healed ridges (group I) or immediately into fresh extraction sockets (group II).
