Although implant therapy in esthetically relevant areas is currently based on a prosthetically driven philosophy, anatomical and technical factors may impair ideal implant placement. In these scenarios, the clinician is frequently asked to solve the discrepancy between the implant emergence and the ideal coronal anatomy of the final restoration. This report describes how changes of the implant abutment-crown contour in specific locations may be intentionally promoted to determine improvements of the peri-implant soft tissues and overall esthetic integration...

Hydraulic sinus lift and augmentation may be successfully performed using a dedicated implant device designed according to residual bone height (RBH). The aim of this study was to evaluate whether a flapless surgical approach might negatively influence the outcome. A total of 40 consecutive patients (16 men and 24 women) were included in the study, 20 in each group (minimal flap/control versus flapless/study). Inclusion criteria were ≥ 3 mm RBH, ≥ 6 mm width of the residual alveolar ridge according to preoperative cone beam computerized tomography, and ≥ 8 mm buccopalatal keratinized gingiva for the flapless group...

The purpose of this study was to evaluate whether the use of removable partial dentures affects the periodontal status of abutment teeth. An observational cross-sectional study was done on a sample of patients rehabilitated with removable partial dentures (2010 to 2013). At a recall appointment, a clinical examination was done to collect data related to the rehabilitation and periodontal status of the abutment teeth. Of 145 invited patients, 54 attended the requested follow-up appointment (37.2%). Mean patient age was 59...

Attached gingiva is desirable for the maintenance of gingival health. Although many methods are used to increase the zone of attached gingiva, the modified apically repositioned flap (MARF) technique has the advantages of simplicity and predictability. The short-term follow-up of the MARF technique demonstrated an increase in keratinized tissue and attached gingiva. This study evaluated long-term results of the MARF technique as used to increase the apicocoronal dimensions of keratinized tissue and attached gingiva in 28 sites (25 patients; average follow-up of 9 years)...

This study evaluated the influence of timing after endodontic treatment and type of resin cement used on the bond strength of fiber posts to epoxy resin-obturated canals. A total of 80 bovine incisor roots were divided into four groups (n = 20). Glass fiber posts were cemented at two different times, immediately or 7 days after endodontic treatment, using either a dual-curing resin cement (RelyX ARC, 3M ESPE) or a self-adhesive resin cement (RelyX U200, 3M ESPE). Following post cementation, the samples were cross-sectioned into slices containing root dentin, cement, and fiber post at the cervical, mid, and apical root thirds...

Pigmentation on gingiva can be physiologic or pathologic. Gingival pigmentation is present from birth in certain individuals. However, sudden occurrence of pigmentation suggests some systemic association. In the present case, a patient was referred by a physician for biopsy of the tissue along with gingival depigmentation. The depigmentation procedure was performed in both arches, and the biopsy specimen was sent for histopathologic examination. This case highlights the importance of biopsy of gingival pigmentation with a history of sudden occurrence...

Given the popularity of dental implants, determining their prognosis is an integral component of dental practice. An accurate prognosis is crucial to development of an appropriate treatment plan and may require alterations as overall status or the status of implants or natural teeth change. The importance of an established set of factors for determining implant prognosis would be highlighted in dentist-patient communication and in interdisciplinary collaboration. The main objective of the proposed prognostication system is short- and long-term success of dental implants...

The success of dental implants depends mainly on osseointegration and gingival sealing. Therefore, early attachment and spreading of epithelial cells might be critical for a positive outcome. Research in dental implant materials has primarily focused on surface roughness, defined by the average roughness (Ra) index, as it promotes the process of osseointegration. This study explored its influence on soft tissue attachment by looking mainly at adhesion, proliferation, and spreading of primary human cells belonging to the epithelial lineage...

Dental therapy of traumatically ankylosed maxillary anterior teeth with an additional slight root resorption represents a great challenge for the restorative team and requires intensive planning and communication between patient, dentist, orthodontist, periodontist, and dental technician. The inhibition of vertical growth often makes dental intervention indispensable. Porcelain laminate veneers have been successfully used for more than two decades, mainly on anterior teeth, and was the minimally invasive treatment option for the present case report...

Maintenance or reconstruction of interproximal papilla for a successful dental implant restoration can be challenging. To date, the results from various surgical and prosthetic techniques to maintain or regenerate papilla adjacent to dental implants have been unpredictable. To maintain the quality of the soft tissue around an implant, the blood supply must be preserved and formation of scar tissue must be minimized during surgery. Therefore, incision design is vital to producing an esthetic and successful dental implant restoration...

A 59-year-old woman was referred for specialist treatment due to peri-implantitis affecting four implants in the anterior maxilla. On presentation, probing depths were up to 12 mm with bleeding on probing/suppuration and extensive peri-implant bone loss. There was a history of treated chronic periodontitis. Nonsurgical management was followed by regenerative peri-implant surgery. Peri-implant probing depths reduced to a maximum of 5 mm and remained stable throughout the 5-year follow-up period. Cone beam computed tomography at 2 years postoperatively confirmed the presence of regenerated peri-implant tissue and integration with the pre-existing peri-implant bone...
