BACKGROUND: Iliac bone grafts are used to augment alveolar ridges followed by subsequent dental implants in completely edentulous patients. In Albania the information about these issues is scarce.AIM: To describe the procedure of iliac bone grafts augmentation of alveolar ridges and evaluate the survival rate of dental implants in completely edentulous patients in Albania.SUBJECTS AND METHODS: Seven totally edentulous patients (three males, average age 45.9 years) presenting at Durrës Regional Hospital during 2008-2015 and seeking a solution to their problem through implantation procedures were included in the study. Patients were thoroughly examined, evaluated and the best augmentation procedure, using iliac crest bone grafts, and dental implantation technique was chosen. The number of dental implants placed was recorded and their survival rate was calculated.RESULTS: The most common intervention site was maxillae (in 71.4% of cases). Dental implants were installed six months after augmentation, all fixed on the very stable augmented alveolar ridge. On average between 20%-30% of bone grafts, volume was resorbed. Of 37 implants settled, 36 of them or 97.3% survived.CONCLUSION: Iliac bone grafts are a suitable augmentation source of bone in a patient suffering from complete edentulism in Albania. The survival rate of dental implants is very satisfactory.

Iliac Bone Graft

Abstract The purpose of this study was to reveal the improvement in facial esthetics and maintenance of mastication in severely atrophied mandibles with inadequate alveolar ridges in 2 patients. Bone graft harvested from iliac crest was used for the reconstruction in the first case, followed by the application of 2 dental implants after 6 months. A free iliac bone graft and 2 dental implants were also used simultaneously with a 1-stage surgery in the second case; the patient had previously had a mandibular reconstruction with a rib graft. Both of the patients achieved remarkably functional and esthetic improvements after treatment. Free iliac bone graft is considered to be a favorable alternative for the maintenance of satisfactory functional and esthetic results in patients with severely atrophied alveolar ridges.

Background. The use of modern digital technologies significantly changes the classical approaches to planning and conducting dental implantation. The whole process can be accomplished performed thus, so that the ideal placement of the implant can be achieved without the injured anatomical structure. Purpose. To evaluate the effectiveness of dental implant placement with the use of 3D-modeling and surgical guided. Materials and methods. A total of 148 patients with ridge defects in age group were selected for the study. All patients had a partially or totally edentulous. Computer scans, three-dimensional computer modeling were used to plan operations. 2 Patient groups were formed to evaluate the effectiveness of treatment using 3D modeling and surgical guided. Patients were included in group I, at the planning stage only a CT scan was used, Group II included patients who underwent a CT scan, 3D computer modeling (3 Shape Implant Studio) during the planning phase, and surgical guided (were fabricated with a desktop 3D printer Stratasys), were used in the surgical phase, the dental defect was restored with the with implant insertion. Results. In Group I, intraoperative or immediate post-operative complications were noted (errors in the position, inclination), anatomical risk structures were invaded, after 3 years producing a survival rate of 96.2 %. In Group II, no intra-operative or immediate post-operative complications were noted (no errors in the position, inclination,), no anatomical risk structures, after 3 years producing a survival rate of 97.6 %. Conclusion. The 3D modeling method and the use of surgical guided for dental implantation significantly risk the complications. Implant placement through the precision surgical guide is more accurate than freehand placement into the osteotomy, the guides allow installation of dental implants in the most optimal position for future prosthetic work, depth, and inclination.

The aim of this study is to compare the survival rate of dental implants with short implants (< 8 mm) and longer implants ( 8 mm) in patients with atrophy of the jaw bones. Materials and research methods. This study is based on the analysis of treatment outcomes in 107 patients, 59 of whom received short implants (< 8 mm) and 48 patients received implants ( 8 mm) using a combination of augmentation. The study determined the engraftment of 5–6 mm Bicon implants and compared it with that of other implant sizes: Results. The average loss of marginal bone after one year was 0.96±0.25 mm for short implants and 0.94±0.46 for long implants. The survival rate of short implants (6–8 mm) after 3 years was 97.8 %, the survival rate of long (10–13 mm) implants was 98.1 %. The patients were satisfied with the aesthetic and functional result of the treatment. The results showed that implantation using short ones is effective in improving the chewing ability of patients in patients with atrophy of the jaw bones. In difficult clinical conditions, with a pronounced bone tissue deficiency, the use of short implants is the most gentle surgical method for restoring the missing support of fixed prostheses. Key words: atrophy of the jaw bones, dental implantation, short implants.

Introduction. Mandible reconstruction is still very challenging for surgeons. Mandible defects could be the consequence of ablative surgery for malignancies, huge jaw cysts, infection and trauma. Segmental resection of the mandible may compromise orofacial function and often lead to patients psychological disorders. Despite very frequent use of microvascular flaps, autogenous bone grafts are still very reliable technique for mandible reconstruction. Comprehensive therapy means not only mandible reconstruction, but prosthodontic rehabilitation supported by dental implants, which can significantly improve patients quality of life. The aim of this paper was to evaluate possible techniques of mandible reconstruction and to present a patient who had been submitted to mandible resection and reconstruction with autogenous iliac bone graft and prosthodontic rehabilitation with fixed denture anchoraged by disc-shaped implants in early loading protocol. Case report. Mandible reconstruction was performed simultaneously with resection. Autogenous iliac bone graft was taken, reshaped and placed in two parts, to the required optimal contour of the mandible. After graft consolidation, decision was made for prosthodontics rehabilitation with fixed dentures supported by implants. In addition to the standard preoperative procedures, planning was done based on a biomodel gained by rapid prototyping after CT scan. It offered a real 3D planning to obtain a proper shape, dimension and the position of implants. Conclusion. If bone dimensions of a reconstructed mandible are insufficient, like in the presented case, the use of basal osseointegrated implants may be a method of choice. Avoiding bone augmentation procedures, as well as early loading protocol for this type of implants, shorten the total rehabilitation time, which is very convenient for patients. Fixed denture supported by dental implants is the best solution for comprehensive rehabilitation after mandible resection.

ABSTRACT Introduction One of the most common and effective ways of replacing missing teeth is by dental implants. Both quality and quantity of bone along with the area of implant placement govern the prognosis of the implant procedure. Certain risk factors predispose the implant treatment to high failure rate. Hence, we assessed the implant patients who were referred from private practitioners to the specialty hospitals from 2010 to 2014. Materials and methods All the patients being referred from private clinics to the specialty dental hospital for the purpose of prosthetic rehabilitation by dental implants from June 2010 to July 2014 were included in the present study. Skilled oral and maxillofacial surgeons were appointed for performing the implant surgical procedures. Prosthetic rehabilitation was done after 6 to 8 weeks and after 10 to 14 weeks in implant cases without and with bone augmentation procedures respectively. Distribution of dental implants based on the indications, location, dimension of augmentation procedure, and complication of implants was analyzed and assessed for the level of significance. Results Of the patients, 712 were females, while the remaining were males. Most of the patients were in the age group of 50 to 59 years. As compared with completely edentulous patients, most of the patients required rehabilitation by a single implant. Maximum dental implants were placed in maxillary premolar region and mandibular first molar region. Over 1,000 cases in this study required rehabilitation by augmentation procedure. Conclusion Partially edentulous patients are most commonly referred to specialized dental hospitals for prosthetic rehabilitation by dental implants, mostly with the purpose of implant placement. Failure rate can be minimized by following strict patient selection protocols along with following a standard surgical criterion. Clinical significance Following standard surgical protocols and strict treatment planning, prognosis of the dental implant procedures can be improved to a greater extent, thereby increasing its clinical success rate.

Edentulous Patients

Dental implants are highly recommended to improve the retention, stability, and support of prostheses in edentulous patients with large surgical defects. Depending on the size of the defect, a bone graft procedure might be necessary. However, due to limitations of bone grafts, some complications might negatively affect the prosthetic rehabilitation of the patient. This case report presents some of these prosthetic problems following surgical resection and autogenous bone graft procedures.

Short Term Survival

The purpose was evaluating the short term survival rate of extra narrow diameter dental implants (2.9 mm, Unitite Slim, S.I.N. Implant System) used to support full-arch mandibular reconstructions. This was a randomized clinical trial analyzing the survival rate of 25 implants measuring 2.9 mm in diameter and 11.5 mm in length (Slim, Unitite, S.I.N. Implant System), and up to 40 N loading torque with immediate loading for protocol-type rehabilitation in the mandible region. Of the 25 implants, 100% remained in function after three months or 180 days of installation. Rehabilitation of total edentulous patients in the mandible with extra-narrow implants (2.9 mm) proved to be effective and promising as an alternative therapy to grafts.
