Consensus conference panel report: crown-height space guidelines for implant dentistry-part 2.

The International Congress of Oral Implantologists sponsored a consensus conference on the topic of Crown Height Space on June 26-27, 2004 in Las Vegas, Nevada. The panel communicated on several occasions before, during, and after the meeting, both as a group and among individuals. A consensus of one opinion was not developed for most issues. However, general guidelines emerged related to the topic. The following article is Part 2 of a summary of several of the guidelines that should be of benefit to the profession at large. (Part 1 appeared in Implant Dentistry 2005;14:312-321.).

Endodontic or dental implant therapy: the factors affecting treatment planning.

BACKGROUND: Clinicians are confronted with difficult choices regarding whether a tooth with pulpal and/or periapical disease should be saved through endodontic treatment or be extracted and replaced with an implant. METHODS: The authors examined publications (research, literature reviews and systematic reviews) related to the factors affecting decision making for patients who have oral diseases or traumatic injuries. RESULTS: The factors to be considered included patient-related issues (systemic and oral health, as well as comfort and treatment perceptions), tooth- and periodontium-related factors (pulpal and periodontal conditions, color characteristics of the teeth, quantity and quality of bone, and soft-tissue anatomy) and treatment-related factors (the potential for procedural complications, required adjunctive procedures and treatment outcomes). CONCLUSIONS: On the basis of survival rates, it appears that more than 95 percent of dental implants and teeth that have undergone endodontic treatment remain functional over time. CLINICAL IMPLICATIONS: Clinicians need to consider carefully several factors before choosing whether to perform endodontic therapy or extract a tooth and place an implant. The result should be high levels of comfort, function, longevity and esthetics for patients.

Designing successful removable partial dentures.

In today's busy dental offices, removable partial denture design is often abdicated by dentists, both as a result of a lack of experience and consensus of design and because of educational failure on the part of dental schools. The result is delegation of the clinical design process to the lab technician. The lack of clinical data provided to the dental technician jeopardizes the quality of care. This article will focus on a logical and simple approach to this problem, making removable partial denture design simple and predictably achievable. The clinical evidence related to removable partial denture design will be described, along with a checklist to simplify the process and make it practical and applicable to everyday clinical practice.

Designing tooth preparations for optimal success.

The form of prepared teeth and the amount of tooth structure remove dare important contributors to the mechanical, biologic,and esthetic success of the overlying crown or fixed partial denture.Therefore, it is important to develop clinical guidelines that can be used to optimize success in fixed prosthodontics.

Five factors to be considered when restoring endodontically treated teeth.

UNLABELLED: Maintenance of tooth integrity and strength is critical to the longevity of any restoration. Endodontic treatment inherently requires reduction of supportive tooth structure to provide access and shape and clean the root canal system. Restorative modalities following root canal therapy must provide sufficient strength for the prosthetic material and tooth structures. This article presents several considerations in the treatment of endodontically compromised teeth to ensure clinical success. LEARNING OBJECTIVES: This article discusses relevant considerations in the restoration of endodontically treated teeth. Upon reading this article, the reader should: Understand the factors that affect the strength of an endodontically treated tooth. Recognize the available restorative options following root canal therapy.

Clinical complications with implants and implant prostheses.

The purpose of this article is to identify the types of complications that have been reported in conjunction with endosseous root form implants and associated implant prostheses. A Medline and an extensive hand search were performed on English-language publications beginning in 1981. The searches focused on publications that contained clinical data regarding success/failure/complications. The complications were divided into the following 6 categories: surgical, implant loss, bone loss, peri-implant soft tissue, mechanical, and esthetic/phonetic. The raw data were combined from multiple studies and means calculated to identify trends noted in the incidences of complications. The most common implant complications (those with a greater than a 15% incidence) were loosening of the overdenture retentive mechanism (33%), implant loss in irradiated maxillae (25%), hemorrhage-related complications (24%), resin veneer fracture with fixed partial dentures (22%), implant loss with maxillary overdentures (21%), overdentures needing to be relined (19%), implant loss in type IV bone (16%), and overdenture clip/attachment fracture (16%). It was not possible to calculate an overall complications incidence for implant prostheses because there were not multiple clinical studies that simultaneously evaluated all or most of the categories of complications. Although the implant data had to be obtained from different studies, they do indicate a trend toward a greater incidence of complications with implant prostheses than single crowns, fixed partial dentures, all-ceramic crowns, resin-bonded prostheses, and posts and cores.

Clinical complications in fixed prosthodontics.

The purpose of this article is to identify the incidence of complications and the most common complications associated with single crowns, fixed partial dentures, all-ceramic crowns, resin-bonded prostheses, and posts and cores. A Medline and an extensive hand search were performed on English-language publications covering the last 50 years. The searches focused on publications that contained clinical data regarding success/failure/complications. Within each type of prosthesis, raw data were combined from multiple studies and mean values calculated to determine what trends were noted in the studies. The lowest incidence of clinical complications was associated with all-ceramic crowns (8%). Posts and cores (10%) and conventional single crowns (11%) had comparable clinical complications incidences. Resin-bonded prostheses (26%) and conventional fixed partial dentures (27%) were found to have comparable clinical complications incidences. The 3 most common complications encountered with all-ceramic crowns were crown fracture (7%), loss of retention (2%), and need for endodontic treatment (1%). The 3 most common complications associated with posts and cores were post loosening (5%), root fracture (3%), and caries (2%). With single crowns, the 3 most common complications were need for endodontic treatment (3%), porcelain veneer fracture (3%), and loss of retention (2%). When fixed partial denture studies were reviewed, the 3 most commonly reported complications were caries (18% of abutments), need for endodontic treatment (11% of abutments), and loss of retention (7% of prostheses). The 3 most common complications associated with resin-bonded prostheses were prosthesis debonding (21%), tooth discoloration (18%), and caries (7%).

Factors affecting the survival of implants placed in grafted maxillary sinuses: a clinical report.

Many factors affect the survival rate of osseointegrated implants placed in grafted maxillary sinuses. This clinical report describes the retrospective evaluation of 60 patients with 228 implants placed in 84 grafted maxillary sinuses at the Loma Linda University School of Dentistry. The factors used to determine the survival rates of these implants were implant type, simultaneous/delayed implant placement, pretreatment bone height, oral hygiene, and cigarette smoking habits. Out of the total 228 implants, 205 (89.9%) remained in function after a mean follow-up period of 41.6 months (range 0 to 60 months). A higher failure rate was associated with the use of non-threaded implants, poor oral hygiene, and smoking. This information may facilitate treatment planning and enhance communication between the dentist and patient regarding the risk/benefit ratio and outcomes of implants placed in grafted maxillary sinuses.

A multicenter interracial study of facial appearance. Part 1: A comparison of extraoral parameters.

PURPOSE: This study was undertaken to compare the facial appearance of patients from six racial groups (African American, Caucasian, Chinese, Hispanic, Japanese, and Korean) for interracial and/or gender differences and to determine if "norms" existed. MATERIALS AND METHODS: A total of 253 subjects (144 men and 109 women) ranging in age from 18 to 41 years (mean age 26.5 years) were evaluated using a standardized protocol. The data were collected and analyzed to establish reference ranges for seven frontal and six profile extraoral parameters. Mean scores were compared by race and gender using a one-way analysis of variance, followed by the Tukey-Kramer test for honestly significant difference when statistically significant differences were found (P < .05). RESULTS: There were no significant differences for any of the seven frontal or six profile extraoral parameters between men and women. No significant differences were found between racial groups for five of the seven frontal and one of the six profile extraoral parameters. CONCLUSION: Most of the frontal facial parameters and one profile extraoral parameter might be considered norms for male and female patients of different ethnic origins. Additional research with larger patient populations would be needed to confirm or refute these trends.

A multicenter interracial study of facial appearance. Part 2: A comparison of intraoral parameters.

PURPOSE: This article compares interracial or gender differences of six intraoral dental parameters among six racial groups (African American, Caucasian, Chinese, Hispanic, Japanese, and Korean). MATERIALS AND METHODS: The same 253 patients participating in part 1 were included in this portion of the study to evaluate six intraoral parameters. The data were collected and analyzed using a one-way analysis of variance, followed by the Tukey-Kramer test for honestly significant difference when statistically significant differences were found (P < .05). RESULTS: Women displayed significantly more gingival tissue in four of the six races, and African Americans displayed significantly more gingival tissue than any other race. Women had significantly more missing teeth than men in three of the six races studied. Japanese subjects had significantly fewer missing teeth and smaller maxillary central incisors than all other groups except Caucasians. Women had significantly narrower maxillary central incisors in three of the races. There was a significantly higher prevalence of Angle Class III relationships in Chinese subjects. The Japanese had significantly more Class II molar relationships than other races. CONCLUSION: Racial and gender differences were found in gingival tissue display, the number of missing teeth, maxillary right central incisor crown width, and Angle molar classification, but not in the amount of vertical or horizontal overlap of the anterior teeth.
