Extraction-site alveolar remodeling is a major concern due to negative volumetric hard and soft tissue changes that inevitably limit rehabilitation options and diminish esthetic outcomes. Surgical techniques employed to minimize alveolar dimensional changes are not always predictable. Utilizing socket-shield with immediate implant surgical procedure provides maintenance of a thin portion of the root in the vestibular area that minimizes bone resorption especially at the coronal cortical aspect. This case series assesses the dimensional changes in peri-alveolar structures via superimposition of the pre-operative and six-month post-operative 3D digital quantification of soft tissue...

PURPOSE: This in vivo study in a canine model assessed the effect of recombinant human platelet-derived growth factor (rhPDGF) on healing of periapical tissues following apical surgery. MATERIALS AND METHODS: Sixty-four premolar teeth of six 2-year-old beagle dogs were randomly assigned to 4 experimental groups; 16 teeth each. In each tooth, coronal access was done, and the pulp extirpated. The teeth were then left open to the oral cavity for one week and then sealed with IRM for 8 weeks...

A clinical observation usually encountered after vestibuloplasty or interventions aiming at deepening the vestibule with or without simultaneous free epithelialized grafts in the posterior ridges is that they are subjected to major dimensional changes attributed to the buccinator fibers attachment. Hence, this study aimed at assessing the attachment of the buccinator muscles in relation to other anatomical landmarks. An ex-vivo study was performed in cadaver heads to explore the association of fibers attachment in relation to the distance from the crestal aspect of edentulous alveolar process (CAP) and the vestibular depth (VD), crestal band of keratinized mucosa (KM), and ridge height (RH)...

AIMS: Aim of this retrospective study was to evaluate the incidence of complications and to determine the long-term survival rate of teeth with severely compromised clinical crowns treated with minimally invasive crown lengthening (MICL) and restorative treatment. METHODS: A sample of 112 teeth in 86 patients was treated with MICL and restorative dentistry. Endodontic and orthodontic therapy was applied when needed. Clinical outcomes were assessed at baseline, 1 year and long-term...

Currently, the incision design for periodontal and implant surgeries is mainly based on the surgeon's personal preference. The primary aim of this study is to review the intricate periodontal microvascular system and to illustrate the potential impact of commonly applied flap designs on the integrity of this system. A complete literature electronic search resulted in 37 relevant articles. The maxillary, facial, and lingual arteries supply the microvasculature system, including the supraperiosteal, intraligamental, and intraosseous arterioles...

This study assessed the effectiveness and predictability of a readily available protocol to treat peri-implantitis utilizing mechanical debridement, chemical antiseptic surface detoxification, and osseous grafting. Nine patients (7 women, 2 men; mean age: 56.5 years) with 15 implants with peri-implantitis were included. Pocket probing depth (PPD), bleeding on probing (BOP), and standardized digital periapical radiographic measurements were taken. Surgical flaps were elevated, and the implant threads were cleaned with a plastic curette...

The aim of this case series was to evaluate the clinical performance of a new volume-stable collagen matrix (VCMX) in combination with the modified coronally advanced tunnel technique (MCAT) for the treatment of gingival recessions. Thirteen patients with a total of 33 maxillary RT1 single and multiple gingival recessions were included in the study. Probing pocket depth (PPD), recession width (RECW), recession depth (REC), height of keratinized tissue (HKT), and gingival thickness (GT) were assessed at baseline and at the 12-month follow-up...

This investigation was designed to evaluate clinical feasibility of the use of narrow-diameter implants to support mandibular overdenture. Twelve patients presenting with an edentulous mandible were recruited from 9 dental offices (n=1~2 per office). Each patient received two to four implants in the mandible. The implants were placed without additional bone augmentation. 36 implants were placed in total. All achieved satisfactory crestal bone stability and soft tissue maintenance at 1 year post final prosthetic restoration...

Minimally invasive nonsurgical treatment (MINST) aims to remove an etiology with minimal damage to the healthy periodontium and provide the ideal healing environment. This case series introduces the novel protocol of laser-assisted MINST (LAMINST), combining minimally invasive surgery with a dental laser. A total of 25 patients (32 teeth) with advanced periodontal disease were enrolled and received periodontal treatment by following the LAMINST protocol. Probing depth (PD), recession, clinical attachment level (CAL), bleeding on probing (BOP), plaque presence, and site mobility were evaluated preoperatively and at 6 months...

Esthetics is important for any dental implant but crucial for implants in the anterior region. Restorations in this region are demanding, and the goal of re-establishing an attractive smile without revealing differences from the natural teeth is difficult to achieve. The aim of this study was to examine the clinical success of the socket-shield technique regarding soft tissue stability and overall esthetic outcome. Pink esthetic scores (PESs) were collected at two time points (T1: 6 months; T2: 6 years) by three different specialists...

Periodontal intrabony defects (IBDs) are commonly encountered in dental practice and are usually treated by open flap debridement (OFD) with or without bone grafts and/or guided tissue regeneration (GTR), platelet-rich fibrin (PRF), or other additives. A difficulty with these approaches is maintaining the space for bone growth at the determined location. In this report, autologous sticky bone (ASB) was used and compared to a simple mixture of PRF and bone graft (PRF-BG) using the identical graft material-bioactive glass morsels-to assess its regenerative potential in IBDs, as sticky bone is known to maintain the space, according to previous research...

This randomized controlled trial aimed to determine the clinical efficacy of xenogeneic collagen membrane (XCM) derived from porcine peritoneum in combination with a coronally advanced flap (CAF) in the management of gingival recession defects and to compare the outcomes to those of connective tissue grafts (CTGs). A total of 12 systemically healthy individuals presenting with 30 isolated/multiple Cairo RT 1/2 gingival recession defects in maxillary canines and premolars were randomly treated either with CAF + XCM or CAF + CTG...

PURPOSE: To investigate the effects of experience level on the clinical and esthetic results of coronally advanced flap (CAF) surgery. MATERIAL AND METHODS: A postgraduate student's first 40 CAF operations in the periodontology residency program were followed. The Miller Class I gingival recessions were divided into four chronologic groups (n: 10 in each). Clinical and esthetic evaluations were performed at baseline and after 6 months. The results of chronologic intervals were statistically compared...

OBJECTIVES: To quantify the buccal bone thickness, area, and perimeter following guided bone regeneration (GBR) using stabilizing periosteal sutures. The loss in hard tissue volume may impair proper implant placement. GBR has been used to regenerate the lost alveolar ridge prior to or at the same time as dental implant placement. The most important factor for GBR success is graft stability. The periosteal mattress suture (PMS) stabilizing technique is an alternative to pins and screws to stabilize bone grafting material and has the advantage of not requiring the removal of the fixing devices...

PURPOSE: To retrospectively evaluate the influence of prosthetic features on marginal bone level changes around bone-level implants with an external hex connection. MATERIALS AND METHODS: A total of 100 patients with 166 implants and cemented crowns were included. Demographic and clinical data were collected. Prosthetic features were radiographically evaluated, including emergence angle (EA), emergence profile (EP), crown-implant ratio (CIR), and abutment height...

Recurrent benign gingival lesions occurring in the anterior dentition are clinical dilemmas. While complete removal of such lesions is required to prevent recurrence, this can result in a poor esthetic outcome. Relative to this conundrum, this report discusses the diagnosis, psychologic management, and clinical treatment of two patients with recurring lesions on the facial gingiva of the mandibular and maxillary incisors, respectively. Patient A, a 55-year-old woman, presented with a recurrent peripheral ossifying fibroma (POF); Patient B, a 76-year-old man, presented with a recurrent pyogenic granuloma (PG)...

The Custom Alveolar Ridge Splitting (CARS) technique was recently reported as a less-invasive treatment option for augmentation of the maxillary anterior area in cases where alveolar width deficiency exists due to bone resorption and remodeling. This technique creates an intraosseous defect to improve success when horizontal ridge augmentation is attempted. The purpose of the present case report was to demonstrate implant placement in an atrophic posterior mandibular site using the CARS technique. This technique was used in the mandibular right second premolar area, followed by placement of a single implant...

PURPOSE: To investigate the effect of erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser conditioning on dentin bond strength and nanoleakage of different universal and self-etch adhesives. MATERIALS AND METHODS: A total of 84 intact human third molar teeth were cut at the dentin level, and half of them were laser conditioned. The specimens were divided into three groups; two different universal resins and one self-etch adhesive resin were applied and composite resin restorations were created...

PURPOSE: To evaluate the marginal leakage of three different types of bonding agents used with two posterior composites and a giomer, available commercially. MATERIAL AND METHODS: Class II box-only cavities were prepared on 90 mandibular first molars with margins extending 1 mm beyond the cementoenamel junction. The samples were divided into nine groups based on three different bonding agents, two different composites, and a giomer. Cavities were restored per the manufacturer's description...
