ABSTRACT
Traumatic injuries or congenital malformations may cause soft and hard tissue defects resulting in the loss of alveolar bone and attached mucosa. Restoring the defective area presents a challenge for clinicians. The prosthetic rehabilitation of 2 patients with maxillary dentoalveolar defects with 2 different prosthetic designs is presented. The esthetic and functional requirements of the patients were fulfilled.

In an abutment screw fracture, it is generally a challenge for the clinician to remove fractured fragments. In some cases, the screw cannot be removed, and alternative solutions should be considered. This clinical report describes the replacement of a ball attachment with a fractured screw, which was impossible to retrieve, with a cast dowel with ball attachment. The patient who presented to the Department of Prosthodontics, Yeditepe University, Faculty of Dentistry was a 65-year-old woman, wearing a mandibular complete denture supported by two implants for 4 years. She complained about the loss of retention of the denture because of the fractured abutment screw, and it was found that another dentist had previously tried to retrieve the fractured screw with no success. It was decided to construct a cast dowel with ball attachment to improve retention without sacrificing the implant. The interior of the implant and the fractured screw were machined with a rotating instrument. An impression was taken with a metal strip and silicone-based materials. In the laboratory, a stone die was generated from the impression, and a custom-made cast dowel with ball attachment was constructed. It was then cemented with glass ionomer cement and connected to the denture with the direct method. The alternative procedure described in this clinical report was successful for the removal of the fractured abutment screw and use of the existing denture.

This article reports on the treatment of edentulous maxillary and mandibular arches with implant-supported fixed partial dentures. Treatment planning and surgical and restorative techniques are reviewed. Preoperative computerized tomography was obtained and computer software was used to determine the final position of the implants and restorations. The outcome has been favorable both for the patient and the clinicians.

AIM: The purpose of this case report is to present the esthetic and functional rehabilitation of the teeth in a 22-year-old patient with Amelogenesis imperfecta (AI). BACKGROUND: AI is a group of hereditary defects of enamel, unassociated with any other generalized defects. It is a rare developmental abnormality of the enamel, with a variable occurrence of approximately 1:4000 to 1:14000 in Western populations. Al results in poor development or complete absence of the enamel of the teeth caused by improper differentiation of the ameloblasts. REPORT: This report describes the diagnosis and treatment of a young male patient with AI and missing molar teeth using contemporary restorative strategies. Initially, the tooth surfaces were treated with a professional cleaning along with conservative restorative treatment. Later, metal-ceramic crowns for posterior teeth and full-ceramic crowns for anterior teeth were utilized for final restorations. SUMMARY: The complexity of the management of patients with AI supports the suggestion the dental profession should have appropriate methods for the rehabilitation of rare dental disorders. The treatment of patients with AI should start with early diagnosis and intervention to prevent later restorative problems.

Bone defects at the anterior regions of the jaws often cause esthetic problems such as gingival disharmonies and longer crowns than neighboring teeth. Variety of procedures can be used in this region for achieving sufficient bone volume with or without different bone graft materials. All of these procedures has their own advantages and disadventages. New bone formation was defined with orthodontic tooth movement in different regions. In this case we present the use of orthodontic tooth movement, for achieving sufficient bone volume, in anterior maxillary region, for esthetic and functional results.
ABSTRACT
The aim of this study was to examine the correlation of subjective dry mouth assessment (xerostomia) with age, sex, denture type, wear duration, denture stability, subjective discomfort, soreness in denture-bearing tissues, and dissatisfaction with chewing, tasting, or speaking in a group of elderly Turkish removable denture wearers. The participants of this study were 229 healthy subjects, 101 males (mean age: 68.1+/-5.2 years) and 128 females (mean age: 66.4+/-4.2 years), all aged 60 years and above. A self-administered structured questionnaire on sensation of dry mouth, its effects in the oral mucosa and ability in the oral functions were given to the participants. Associations of the categorical variables were examined using the chi(2)-test (p<0.05). Satisfaction in the ability of speaking, tasting foods, chewing hard food was determined statistically significant in patients without dry mouth (p<0.05). Overall satisfaction of dentures was significantly higher in patients without dry mouth (p<0.05). Participants with having dry mouth reported soreness in denture-bearing tissues in both complete and removable partial denture (RPD) wearers. It was also found that oral dryness significantly affects oral functions in terms of the satisfaction with removable denture and the ability in the oral functions independent to education level or gender.

OBJECTIVE: The purpose of this study was to evaluate the relationship between the quality of root canal fillings and type of permanent coronal restorations and their association with the periapical status in a Turkish subpopulation. STUDY DESIGN: There were 1268 endodontically treated teeth from 280 panoramic radiographs that were evaluated. Two observers assessed the radiographs using an x-ray viewer with 2 times magnification. Teeth were classified according to the type of restorations. The quality of root canal fillings were evaluated according to the criteria determined by Tronstad et al. Apical status was assessed by the Periapical Index scores (PAI) proposed by Ørstavik et al. Chi-square test was used for statistical analysis. RESULTS: There were 59.5% of endodontically treated teeth that showed healthy periapex. Teeth with good endodontic treatment showed statistically significant high healthy periapex rates regardless of the type of the restoration. In addition, the evaluation of the entire material also showed that the roots with posts had significantly more periapical pathosis than roots without posts (P = .001). CONCLUSIONS: It can be concluded that, although the quality of the root canal filling plays a key role in the outcome of endodontic therapy, the type of restoration can also be a contributing factor in the treatment outcome.
