Aesthetic versus surgical success of single dental implants: 1- to 9-year follow-up.

Anterior maxillary implantation is a challenging treatment. The authors examined the aesthetic and surgical success of a single dental implant in the anterior by studying 52 implants with a mean follow-up of 37.5 months. Marginal bone loss (MBL), aesthetic parameters, and examiners' satisfaction from the aesthetic outcome were examined. The total surgical survival and success rates as well as the average examiner's aesthetic satisfaction and success rates are presented. Implantation in the anterior has high surgical survival and success rates, as well as a considerably high aesthetic success rate. The high surgical success and survival rates cannot, however, predict aesthetic success.

Malocclusion among 12-year-old school children in Mankweng, Limpopo Province of South Africa.

Consent was obtained from all relevant authorities to undertake an epidemiological survey to determine the occlusal status of a sample of 12-year-old Black school children in Mankweng Circuit, Limpopo Province. The examination was carried out using the Dental Aesthetic Index (DAI) criteria, under conditions prescribed by the WHO in 1987. The results were analysed using the Kotmogorov-Smirnov Test. The results of the study showed that forty seven percent (47%) of the subjects required orthodontic treatment, in the categories: definitive 20%, severe 13% and handicapping 14%. There is a proven need for orthodontic treatment among 12-year-old Black school children in Mankweng. Since there is no government hospital or clinic to provide such treatment, a centre should be established.

The smile buccal corridors: aesthetic value for dentists and laypersons.

The purpose of this study is to assess the aesthetic value of "buccal corridors" on smile attractiveness as judged by dentists and laypersons. In order to evaluate the aesthetic impact of the "buccal corridors", a pleasant smile (frontal view) was scanned (Scanner HP 5490C, 1200 x 1200 dpi) and modified (Adobe Photoshop 5.0) by a professional computer technician. Three pictures have been produced, one with minimal corridors (no 1), another with evident corridors (no 2), and a third one with moderate corridors (no 3). During a survey 1275 laypersons (413 M, 862 F; 14 to 77 years) and 646 dentists (361 M, 285 F; from 25 to 80 years) were asked to indicate the most pleasant and the most unpleasant smile and to fill in a short questionnaire; the data have been statistically evaluated through an ANOVA test. Among the laypersons: 838 (65.72%) chose the first smile; 91 (7.13%) the second one; whereas 346 (27.13%) the third one. The differences are statistically significant (p .05); no statistical differences were found by analyzing the gender and the age of the groups. Among the dentists: 481 (74.46%) preferred the first smile; 44 (6.81%) the second one; whereas 121 (18.73%) the third one, the differences are statistically significant (p .05), no statistical differences were found by analyzing the gender and the age of the groups. Moreover no statistical differences were found by comparing the two different groups. Therefore, a full, broad smile with minimal "buccal corridors" seems to please dentists as well as laypersons and age and gender were not relevant.

[Study of dental chromatic space].

Dental chromatic space has been the topic for many studies and most of all indicated that dental structures are very versatile from the colour point of view, therefore a proper shade selection is difficult to made. Our study made a comparison between the shades of dental structures of men and women of different ages, the measurements being done in three regions: incisal, middle and cervical. We used a spectrophotometer Spectra-Flash 600 and the PC programme Data-Master version 2.3 for both chromatic determinations and the statistical evaluations. The study proved that there are no major differences between the dental shades of men and women; meanwhile chrome increases with age and from incisal to cervical regions. Also, value increases from incisal to cervical region.

Metal-composite copings in the aesthetic restoration of the severely compromised patient.

Aesthetic enhancement of the smile can be as simple as performing tooth whitening or as involved as a full-mouth reconstruction. In instances where porcelain veneers are contraindicated, when subgingival margin placement is required, or when it is necessary to conceal dark substructures or provide occlusal stability, metal-ceramic crowns may be required. This presentation highlights the properties of a metal-composite coping and demonstrates its application in a full mouth reconstruction used by the author to achieve the desired functional and aesthetic outcome.

Orthodontic treatment need in an accredited graduate orthodontic center in north america: a pilot study.

AIM: To assess the objective orthodontic treatment needs of patients treated in an accredited Orthodontic Clinic in North America using a retrospective cross sectional study and the Dental Aesthetic Index (DAI). METHODS AND MATERIALS: One hundred pre- and post-treatment study models were randomly selected from the model storage facility of the clinic. Only the pre-treatment study models were assessed using the DAI. The pre-treatment and post-treatment ages for each case were noted as recorded on the corresponding study models. The range for the pre-treatment age was 10 to 52 years, and from 12 years, 4 months to 54 years for the post-treatment age range. The duration of treatment for each case was calculated by subtracting the pre-treatment age from the post-treatment age (range of treatment duration, 9 to 125 months). Descriptive statistics as well as chi-square statistics were employed to analyze the data. RESULTS: Fifteen cases had normal or minor malocclusions with no treatment or slight need for treatment. Definite malocclusions with treatment highly desirable accounted for 22 cases and severe malocclusion with treatment highly desirable was found in 16 cases. Forty-seven cases had handicapping malocclusion with treatment considered mandatory. While a statistically significant association (p<0.05) was found between duration of treatment and severity levels of malocclusion (DAI scores), the association between pre-treatment age and DAI scores was not significant (p > 0.05). CONCLUSIONS: Eighty-five percent of the study sample needed orthodontic treatment with different malocclusion severity levels, while 47% of the cases qualified for publicly subsidized treatment due to handicapping malocclusions. The association between duration of treatment and DAI score groups (malocclusion severity levels) was found statistically significant. It could be helpful for more clinic-based (demand populations) studies on treatment needs be undertaken across the globe using the DAI, at least for the purposes of comparison.

Selection of luting agents, part 1.

The clinical success of indirect restorations is dependent on multiple factors that include preparation design, mechanical forces, restorative material selection, oral hygiene, and selection of a proper luting agent. The selection of the luting agent is dependent on the specific clinical situation, the type of restoration utilized and the physical, biologic, and handling properties of the luting agent. Although it is important to choose the best luting agent for each clinical situation, far greater variations in physical properties result from improper manipulation of a given luting agent than exist between different types of cements. One study listed loss of retention as the third-leading cause of prosthetic replacement, with failure occurring after only 5.8 years in service. The primary purpose of the luting procedure is to achieve a durable bond and to have good marginal adaptation of the luting material to the restoration and tooth. Conventional cements have always relied upon retention and resistance forms in tooth preparations; Adhesive-type luting agents offer the clinician an added advantage by bonding to the tooth structure. Three main types of conventional "cements" are commonly used, zinc phosphate and the polyelectrolyte cements polycarboxylate, and glass ionomer cements. Because of its long history of successful clinical use, zinc phosphate is considered the gold standard against which all other luting agents are compared because of its long clinical history of successful use. Currently, two additional types of luting agents have gained considerable popularity. These include the resin-modified glass ionomer cements and resin cements. The resin cement category includes light-cured, dual-cured and chemically cured agents. The purpose of this article is to discuss the ideal attributes of a luting agent and make clinical recommendations for their use.

Improving implant aesthetics: prosthetically generated papilla through tissue modeling with composite.

UNLABELLED: Dental implants provide clinicians with a predictable means of replacing the function of lost natural teeth. Whereas innovative restorative materials and techniques have yielded predictable "white aesthetics" for a tooth, comparable success with the "pink aesthetics" of implant restorations has been more problematic. This article describes a technique for improving the aesthetic outcome of implant dentistry by contouring soft tissue around implants through a buildup of composite to a "UCLA-type" abutment. From this technique, it is believed that a similar procedure for other implant systems can be easily and successfully extrapolated. LEARNING OBJECTIVES: This article discusses a technique that allows for implant placement in cases where the emergence profile has been compromised. Upon reading this article, the reader should: Understand why the pink aesthetics of the patient's smile are as important as the "white aesthetics". Learn how to contour the soft tissues surrounding implants.
