Objective: To evaluate bony reconstruction of the atrophic anterior maxilla using particulate grafts with or without autologous bone marrow aspirate concentrate (BMAC).
Materials And Methods: Eight patients with atrophy of the anterior maxilla due to teeth loss were selected and split into groups according to the type of material used: Control Group (CG) (n = 4) - particulate xenograft only and Test Group (TG) (n = 4) - a combination of particulate xenograft and BMAC. Both groups received a collagen membrane to cover the xenograft.
Cranio-maxillofacial malformations, as seen in Crouzon and Apert syndromes, may impose an immense distress on both function and aesthetics of the person affected. The aims of this study were to describe and compare the main facial and intraoral features of patients with Apert and Crouzon syndromes, the clinical manifestations that may be present, additionally to the main syndromic traits, as well as the cranio-maxillofacial surgical treatment protocols followed.Twenty-three patients with Apert syndrome (6 males, 17 females), and 28 patients with Crouzon syndrome (20 males, 8 females) were evaluated for general medical aspects, craniofacial characteristics, dentoalveolar traits before and after the final orthognathic surgery, and types and timing of cranio-maxillofacial operations.

Background: For single-tooth implant replacement in the posterior maxilla, it is often necessary to do an augmentation of the alveolar process because of post-extraction resorption and include part of the maxillary sinus.
Purpose: The purpose of this study is to present a technique for a local sinus lift with autogenous bone in a one-stage procedure. Additionally, volume changes of the grafted area were evaluated radiographically up to 2 years.

Purpose: To study the outcome of implant placement in fresh extraction sockets with simultaneous use of particulate bone graft material.
Materials And Methods: Patients referred to the maxillofacial surgery clinic for extraction and implant therapy were included in the study. A consecutive series of patients suitable for immediate placement in combination with extraction was subjected to implant surgery.

Purpose: The aim of this study was to report the long-term results of a 2-stage sinus lift procedure with autologous bone graft and Astra Tech Tioblast ST implants (Astra Tech, Mölndal, Sweden).
Materials And Methods: Sinus lift procedures were carried out in 36 patients, 25 unilateral and 11 bilateral. Bone grafts were obtained from the iliac crest, mandibular angle, or chin region.
Monochromatic light has been used in many studies and indicated that phototherapy might be effective in the treatment of pain relief. The aim of this investigation was to evaluate the efficacy of monochromatic light phototherapy on patients who had undergone impacted third molar surgery. Sixty adult patients were included in the study.

Purpose: The purpose of this clinical investigation was to evaluate the treatment outcome with zygoma implants with regard to implant survival, patient satisfaction, and function of prosthesis replacement after 3 years.
Patients And Methods: The treatment outcome of 76 patients treated with 145 zygoma fixtures at 16 centers was evaluated with regard to implant survival. Status of peri-implant mucosa and amount of plaque were registered annually.
This article describes the authors' approach to correcting dentofacial skeletal deformities requiring multisegmentation of the maxilla. Achieving optimal results requires a close collaboration within the orthodontic-surgical team. The importance of attention to detail in the course of the surgical procedure cannot be overemphasized, because complications of avascular necrosis cannot be corrected easily.

Mandibular advancement was studied in 32 patients with mandibular retrognathia in whom the only intervention was in the mandible. Fifteen patients were treated with fixation by lag screws and 17 with monocortical miniplates. Lateral radiographs were taken preoperatively, postoperatively, 2 months postoperatively, and 1.

In a long-term prospective study multisegmentation for transverse widening of the maxilla was followed up to calculate tendency to relapse and clinical outcome. Thirty-six patients were followed up for 30 months and 13 for 60 months postoperatively. There were no complications after the maxillary operations.

Purpose: The aim of this study was to report the outcome of using a maxillary osteotomy with an interpositional bone graft and implants in the treatment of extremely resorbed maxillae.
Materials And Methods: Twenty-two consecutive patients (mean age 65.7 years) were included in the study.
Purpose: To evaluate treatment outcome with Zygoma fixtures (Nobel Biocare, Göteborg, Sweden) with regard to fixture survival, patient satisfaction, and function of prosthesis replacement.
Materials And Methods: The treatment outcome of 76 patients treated with 145 Zygoma fixtures at 16 centers was evaluated. Patient's and dentist's evaluations of the functional and aesthetic outcome of the treatment were assessed at delivery of prosthesis and at the 1-year follow-up visit.
Crucial if tooth transplantation is to succeed is preservation of the vitality of the cells of the periodontium and cementum of the tooth graft. Poor contact between the tissues of the recipient site and the root surface when teeth are transplanted to recipient sites prepared immediately prior to transplantation (one-stage technique) could, after transplantation, result in insufficient nutrition to the cells of the root surface and contribute to necrosis of the cells. To improve nutrition, tooth transplantation to recipient beds left to heal for 14 days was performed (two-stage technique).

All four patients had been successfully treated for malignant tumours in the midface during early childhood by use of full dose irradiation. Retarded growth of the maxilla together with missing root formation of permanent teeth prevented the alveolar process to develop.

Background: Previous experimental studies on onlay bone graft integration have shown either advantages or disadvantages to the use of mechanical barriers. This indicates that the role played by the biologic properties of transplanted bone and membrane in graft revascularization and bone remodeling has not yet been established. The outcomes regarding osseointegration of titanium dental implants applied in such a condition are still contradictory.

A total of 37 patients have had chin augmentation procedures with HTR-polymer implants. Indications were mandibular retrognathia in connection with dentofacial deformities in 13 and the remaining 24 had a normal occlusion. Three patients with micrognathia also had juvenile rheumatoid arthritis.

Yet, there is insufficient evidence that such implants show higher stability and an increased survival rate. PURPOSE: The purpose of this investigation was to study the integration and stability of grit-blasted implants with retention elements on the implant neck, with and without marginal bone defects, compared with machined implants without retention elements.
