Zirconia removable telescopic dentures retained on teeth or implants for maxilla rehabilitation. Three-year observation of three cases.

This report addresses maxillary restoration with removable telescopic crown-retained palatal free dentures. One patient with 7 natural teeth (PERIO), a second patient with 6 dental implants (IMPL), and a third patient with 2 natural teeth and 4 dental implants (IMPL-PERIO) were treated. Zirconia copings for natural teeth and individual zirconia implant abutments were fabricated in CAD/CAM and used as primary crowns.

Alveolar bone preservation in extraction sockets using non-resorbable dPTFE membranes: a retrospective non-randomized study.

Background: The aim of this study was to investigate the clinical regeneration of extraction sockets using high-density polytetrafluoroethylene (dPTFE) membranes without the use of a graft material.

Methods: A total of 276 extraction sockets were evaluated in 276 subjects (151 males and 125 females; mean age, 50.2 years; age range: 24 to 73 years).

Use of engineered bone for sinus augmentation.

Background: Tissue-engineered bone grafts represent an appealing alternative for maxillary sinus augmentation because they eliminate the significant drawbacks associated with extra- and intraoral bone-harvesting procedures. In the present case series, we document the outcomes of sinus augmentation surgery using tissue-engineered bone grafts.

Methods: Three patients requiring bilateral sinus augmentation received tissue-engineered bone grafts combined with xenograft prior to implant placement.

Combined periodontal and implant treatment of a case of aggressive periodontitis.

Aggressive periodontitis renders a great challenge to clinicians with regards to treatment and prosthodontic rehabilitation. A compromised remaining dentition and a tendency toward refractory disease make it difficult to establish a treatment plan that renders an adequate long-term prognosis. Although the use of implants has become a common treatment modality, limited data are available on the use of dental implants in patients with aggressive periodontitis, especially for cases necessitating the use grafting procedures preceding implant placement.

Telescopic crowns as attachments for implant supported restorations: a case series.

The use of dental implants to support mandibular or maxillary overdentures is a widely used treatment modality. Advantages are an increase in retention, an increase in chewing ability, and easy access for oral hygiene procedures. While telescopic and conical crowns have been used for decades to connect natural teeth to overdentures, not many cases have been reported in the literature of telescopic crowns placed on implants to support overdentures.

Immediate implant placement: a case series.

A major drawback of implant therapy is the comparatively long healing period involved. Early and immediate loading of dental implants can significantly decrease the treatment time and thus result in an increase in patients' comfort. In this report, 3 cases of placement and immediate loading of the final implants are presented.

Prevalence of maxillary sinus disease and abnormalities in patients scheduled for sinus lift procedures.

Background: The purpose of the present study was to determine the prevalence of sinus disease and abnormalities among patients scheduled to undergo direct sinus augmentation.

Methods: Forty-five patients attending a private periodontal practice and consecutively treatment planned for sinus augmentation were referred for otorhinolaryngologic evaluation, which included a medical history and radiographic (computed tomography), clinical, and endoscopic examinations. Pathological findings were recorded and otorhinolaryngologic treatment was provided.
