The success of dental implant therapy in the esthetic zone requires not only functional osseointegration but also favorable esthetic results. The greatest challenge in the esthetic zone is to establish harmony, balance, and continuity of gingival form between implant restorations and the adjacent natural teeth. In the esthetic zone, a localized ridge defect or loss of a peri-implant papilla is common and can be corrected via soft tissue augmentation. This case report describes a novel surgical technique using connective tissue grafts via an apical pouch to increase soft tissue volume over an alveolar ridge defect or around natural teeth or implants in the maxillary anterior area...

The resin-bonded fixed partial denture (RB-FPD) is the first restorative treatment option to be considered in cases where one or more teeth are missing. The indications for implants, conventional FPDs, and adhesive FPDs, considering the general and dental conditions of the patient, are discussed in this article. When the RB-FPD is the chosen option, a direct or indirect technique, a cantilever-type or fixed-fixed design, and materials to be used need to be selected. The choice will depend on a variety of factors, such as interproximal space at the connector area, anterior or posterior location, the skills of the dentist, esthetics, and the patient's wishes...

Both hard and soft tissue undergo change after tooth extraction. In particular, the bone tissue surrounding teeth with fenestration or dehiscence defects undergoes dramatic change following tooth extraction, which can compromise further rehabilitation of the area. Adequate alveolar bone volume and keratinized mucosa are critical to the success of implant therapy. Therefore, the anatomic dimension of the alveolar ridge must be adequate to achieve an esthetically acceptable outcome of implant therapy. Previous studies have proposed many clinical techniques for preserving the extraction socket...

OBJECTIVES: The present randomized controlled trial aimed to assess the effect of hyaluronan (HY) injections to augment deficient interproximal papillae at implant-supported crowns in the anterior maxilla. METHODS: Twenty-two patients with a deficient papilla in the anterior maxilla next to an implant-supported crown were randomly assigned to receive twice either HY (test) or saline solution (control) injection. The following parameters were recorded prior to injection (baseline) and 3 and 6 months after injection: distance between the papilla tip and contact point (PT-CP), modified papilla index score (MPIS), and standard clinical periodontal parameters...

The aim of this study was to test whether zirconia abutments exhibit the same clinical and esthetic outcomes as titanium abutments in single-tooth implant restorations in the esthetic area. The 24 treated patients were randomly assigned to a test (zirconia abutment) or control (titanium abutment) group. Objective evaluations were carried out using the Implant Crown Aesthetic Index (ICAI) and the Papilla Index (PI) at the 1-month and 12-month follow-up examinations after crown cementation. No significant differences, either in ICAI or in other periodontal or radiographic measurements, were observed...

This study evaluated volume stability after alveolar ridge contouring with free connective tissue grafts at implant placement in single-tooth gaps. A total of 52 single-tooth gaps with labial volume deficiencies in the maxilla (incisors, canines, and premolars) were consecutively treated with implants and concomitant free palatal connective tissue grafts in 46 patients between 2006 and 2009. Implants had to be covered with at least 2 mm peri-implant local bone after insertion. At implant placement, a free connective tissue graft from the palate was fixed inside a labial split-thickness flap to form an existing concave buccal alveolar ridge contour due to tissue volume deficiency into a convex shape...

The most important objectives in restoring the maxillofacial patient are the restoration of function and psychological improvement through esthetics. Acquired maxillary and mandibular defects due to significant trauma or surgery represent a major challenge for the clinician and patient. Dental implant-retained prostheses represent a well-documented and reliable treatment option and can also help patients with maxillofacial defects by eliminating denture instability and improving function. Full-arch fixed dental hybrid prostheses provide functional and psychological advantages and also reduce the load on vulnerable soft and hard tissues in the reconstruction area...

Adult orthodontics has been an area of increasing focus in recent times. Comprehensive treatment of adults is more challenging due to a myriad of problems that coexist in an adult that makes treatment planning more challenging. A large number of individuals seek dental care because of aesthetic reasons, that is, the desire to look more attractive by improving their smiles. The role an attractive smile plays on a person's self-image and confidence cannot be overemphasized. Evaluating and treating patients for the purpose of smile design often involves a multi-discipline approach...
