OBJECTIVE: This study aims to collect data on implant survival, bone volume maintenance, and complications associated with the socket shield technique. BACKGROUND DATA: The socket shield technique was introduced in 2010. Since then, several systematic reviews have been published, showing good clinical outcomes. The behaviour of the buccal bone plate is so far not completely understood. METHODS: The study involved the placement of 23 implants using the socket shield technique in 20 patients...

Developing biomaterials capable of promoting bone regeneration in bacteria-infected sites is of utmost urgency for periodontal disease therapies. Here we produce a hybrid hydrogel by integrating CuS nanoparticles (CuSNPs), which could kill bacteria through photothermal therapy (PTT) triggered by a near infrared (NIR) light, and a gelatin methacryloyl (GelMA) hydrogel, which is injectable and biocompatible. Specifically, CuSNPs were precipitated by chitosan (CS) firstly, then grafted with methacrylic anhydride (MA) to form CuSNP@CS-MA, which was photo-crosslinked with GelMA to synthesize hybrid hydrogels (GelMA/CuSNP)...

Pediatric craniomaxillofacial reconstruction must be approached through the lens of growth and durability. A systematic approach of matching defects to donor tissue drives the selection of autologous donor material. The menu of available techniques for reconstruction can be organized in a ladder, similar to adults, with additional considerations. Reconstructive surgeons have the opportunity to promote and maintain young patients' sense of identity during their psychosocial development.

Although transcrestal sinus floor elevation (TSFE) is widely used for cases of insufficient residual bone height in the posterior maxilla, few studies have focused on the risk factors of early implant failure associated with TSFE procedures. This study aimed to identify and summarize the possible risk factors of implant failure associated with TSFE to ensure a more predictable implant survival rate using TSFE. We report the treatment of a patient with implant failure following TSFE and discuss this case's possible associated risk factors...

We evaluated the effect of periosteal-releasing incisions on flap displacement in anterior maxillary sites following implant placement and simultaneously guided bone regeneration. Thirty patients requiring a single dental implant and guided bone regeneration in the maxillary esthetic zone were recruited. After full-thickness flap elevation, the displacement of the flap was measured under a standardized tension of 1 Ncm. Then, a two-step periosteal releasing incision was placed in the internal aspect of the flap, and the displacement was remeasured using the same standardized tension...

The most challenging and time-consuming step in the free gingival graft (FGG) for keratinized mucosa augmentation is the compression suture anchoring the FGG to the periosteum. This article proposed a novel "microscrew with tie-down sutures" technique to anchor the FGG to the recipient site without the traditional trans-periosteum suture. This patient's keratinized mucosa width (KMW) around the healing abutments of teeth #29 and #30 was less than 1 mm. After an apically positioned flap (AFP) was prepared, 2 microscrews were placed at the buccal plate of the alveolar ridge bone, which is the coronal margin of the AFP...

This retrospective study aimed to evaluate success rate of guided bone regeneration (GBR) bone grafting and investigate survival rate of implants, as well as degree of marginal bone loss (MBL) around implants. This study was carried out between January 2007 and December 2016 on treatment outcomes of patients with implants which used various graft materials, including autograft, allograft, and xenograft. The bone graft success rate and implant survival rate were recorded. The influence of confounding factors such as patient characteristics, bone graft properties, and implant conditions was considered...

In this study, we aimed to provide guidance for selecting bone grafting materials in cases of alveolar clefts. Twenty-nine patients with unilateral complete alveolar clefts were categorized into three groups based on the bone grafting material used: Group A (iliac bone block grafts), Group B (iliac cancellous bone grafts), and Group C (chin bone block grafts). Cone-beam computed tomography (CBCT) data were analyzed using Mimics 19.0 software. Results showed that Group A had the highest bone formation rate, with significant differences observed between Groups A and B, as well as between Groups B and C...

INTRODUCTION AND IMPORTANCE: Aliments such as congenital conditions, pathological, and iatrogenic circumstances may result in mandibular defects that can severely disturb the patients' oral health, functions (mastication, speech), aesthetics, and quality of life and present a rehabilitating challenge. CASE PRESENTATION: we present a multidisciplinary treatment approach for three cases presented with mandibular resection as a consequence of cystic, benign, and malignant tumour eradication that were rehabilitated with immediately loaded fixed corticobasal implant-supported prostheses and a follow-up period of 5,5 and 4 years...

OBJECTIVE: To compare histologically the percentage of bone formation 12-20 weeks post-ridge augmentation using two different techniques. BACKGROUND: Tooth loss is associated with three-dimensional bone remodeling and ridge atrophy. Ridge preservation procedures can prevent alveolar bone volume loss. Different techniques and materials are used to preserve the alveolar ridge. MATERIALS & METHODS: Computer-generated randomization software was used to assign two ridge preservation techniques for 11 extraction sites...
