Emphysema after Sinus Grafting: Importance of Patient's Information, Early Diagnosis, and Management.

The sinus elevation procedure is a safe and predictable technique that allows the placement of implants in atrophic posterior maxillae. However, some recommendations have to be followed by the patient to ensure reliable healing. It is particularly important to avoid inducing trauma in the region concerned and through the sinuses.

Development of a surgical guide for minimally invasive corticotomies with a complete digital intraoral and laboratory workflow.

Aim: Surgically facilitated orthodontic treatment is increasingly being used, especially for adults, to facilitate tooth movements and reduce the duration of orthodontic treatment.

Osteotome Sinus Floor Elevation Without Grafting: A 10-Year Study of Cone Beam Computerized Tomography vs Periapical Radiography.

This article aims to evaluate and compare the 10-year bone anchorage and protrusion of implants into the sinus using cone beam computerized tomography (CBCT) and periapical radiography. Implants (≤ 10 mm) were placed with osteotome sinus floor elevation (OSFE) without grafting in maxillae with bone height ≤ 8 mm. After 10 years, the CBCT analysis showed bone presence at the buccal and palatal implant sides and corroborated the results obtained using periapical radiographs.

Purpose: To evaluate the thickness of the sinus membrane in contact with implants inserted 10 years before using an augmentation procedure without grafting material, and to identify adverse events correlated with implant protrusion in the sinus.

Materials And Methods: Osteotome sinus floor elevations were performed without grafting material. The implants (Straumann AG, Basel, Switzerland) were placed simultaneously, all protruded into the sinus.

Unusual Etiology and Diagnosis of Oroantral Communication due to Late Implant Failure.

Oroantral communication (OAC) rarely occurs long after implant placement. The present report describes the rare etiology and the difficulty of the diagnosis of an uncommon OAC occurring 10 years after the implant placement in the posterior maxilla. The difficulty of the diagnosis lies in the absence of clinical symptoms of sinusitis and presence of multiunit prosthesis hiding implant failure.

Short Implants Placed with or without Grafting in Atrophic Sinuses: The 3-Year Results of a Prospective Randomized Controlled Study.

Background: The question whether a minimal maxillary residual bone height (RBH) allows the predictable use of osteotome sinus floor elevation (OSFE) remains unresolved.

Purpose: To evaluate the efficacy of short implants placed with OSFE in an RBH of ≤4 mm and to compare bone levels around implants placed with (control) or without (test) grafting after 3 years.

Materials And Methods: Eight-millimeter implants were placed by OSFE in sinuses randomized to receive anorganic bovine bone or no grafting material.

Paradigm shift in the management of the atrophic posterior maxilla.

When the posterior maxilla is atrophic, the reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome sinus floor elevation technique and without graft can be proposed for an efficient treatment of clinical cases with a maxillary residual bone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ≤4 mm.
