Positive effects of platelet-rich fibrin (PRF) on soft tissue healing are well documented, but its role in hard-tissue healing remains contested. The present case series documents the use of PRF as the sole grafting material in periapical bone defects. PRF was prepared and condensed into the bone defects after debridement. The defects were then covered with a collagen membrane and wound closure was performed. In all three cases presented in this report, excellent bone fill was observed in the periapical defects...

Appropriate regeneration of periodontal tissues is the primary purpose of periodontal disease treatment. The present study assessed the impact of three key regenerative elements-platelet-rich plasma (PRP), canine bone marrow mesenchymal stem cells (cBM-MSCs), and fibrin glue-on periodontal regeneration. In each of the study's five dogs, Class II furcation defects were established on the buccal surface of five teeth. One tooth (five total) from each dog was placed into one of five groups: (1) PRP + fibrin glue, (2) PRP + fibrin glue + cBM-MSCs, (3) fibrin glue, (4) cBM-MSCs + fibrin glue, and (5) control (no treatment)...

This article describes two case reports of immediate full-arch dental implant- supported prostheses using facial parameters to determine the anticipated incisal edge (AIE) position. Treatment planning the terminal dentition is driven by several facial parameters. A frontal photo is obtained to assess the facial thirds and the symmetry in the lower third. A profile photo allows the clinician to measure Holdaway's angle, nasolabial angle, and labiomental sulcus depth and anatomy. Facial assessment is a diagnostic tool that assists the clinician in addressing the challenges of ideal tooth position in the absence of dental landmarks to achieve dentofacial esthetics...

Double lip is a rare deformity that mainly affects the upper lip. The typical clinical image involves bilateral mucosal pads separated by a central groove that appear superimposed over the maxillary incisors. The deformity is rather noticeable and esthetically disturbing. Most cases of double lip are congenital, but syndromic appearance of double lip has been described. Surgical reduction of the tissue surplus is the treatment method of choice. The literature suggests excision of excess mucosa and the underlying tissues to correct double upper lip...

The computer-assisted design/computer-assisted manufactured compound prosthesis involves designing and milling a cement-retained prosthesis over milled titanium bars. In the presented clinical case report, a diagnostic wax pattern was made to assess esthetics, contours, and occlusion. A total of eight maxillary root-form implants were restored by following the combined prosthesis design concept. The mandibular arch was restored with a screw-retained implant-supported zirconia fixed prosthesis. A milled polymethyl methacrylate (PMMA) maxillary interim prosthesis was fabricated to intraorally confirm the diagnostic wax pattern...

Predictable and effective surgical techniques that aim to increase the width of keratinized gingiva, relocate the mucogingival junction, and deepen the vestibule often involve soft tissue autografts; however, soft tissue autograft supply is limited and its harvesting is associated with patient morbidity. With a strip autograft and xenogeneic collagen matrix (XCM) technique combination, autograft harvest requirements and patient morbidity are reduced. In this histologic evaluation, 12 strip autograft/XCM biopsy samples were compared with 3 reference samples of palatal strip autografts...

The aim of this case-control study was to evaluate the influence of soft tissue thickness at implant placement (thin [< 3 mm] vs thick [≥ 3 mm]) and bone volume (abundant vs limited) on initial crestal bone remodeling of immediate postextraction and delayed (healed site) implants in immediate loading situations. A total of 67 patients with 133 implants could be evaluated, of which 77 were placed immediately after extraction and 56 in healed ridges. If sufficient bone volume is present and primary stability is achieved, immediate loading of the implant yields good clinical and radiographic outcomes, yet implants placed in healed ridges with thin soft tissues are more prone to initial crestal bone loss...
