An up to 20-year retrospective study of 4-unit fixed dental prostheses for the replacement of 2 missing adjacent teeth.

Purpose: This study evaluated treatment outcomes of 4-unit porcelain-fused-to-gold fixed dental prostheses (FDPs) replacing 2 adjacent missing teeth.

Materials And Methods: A total of 102 FDPs made in an undergraduate university clinic for 73 patients were evaluated for up to 20 years, with a mean survival follow-up time of 11.4 years.

Long-term results of short-span versus long-span fixed dental prostheses: an up to 20-year retrospective study.

Purpose: This study of short-span fixed dental prostheses (Ss-FDPs) versus long-span FDPs (Ls-FDPs) evaluated the long-term efficacy and determined the frequencies and causes of failures.

Materials And Methods: A total of 236 Ss-FDPs and 86 Ls-FDPs made in an undergraduate university clinic for 149 and 70 patients, respectively, were evaluated over a 20-year period. Kaplan-Meier analysis with a 95% confidence interval was used to estimate the survival probability.

The influence of gender and age on fixed prosthetic restoration longevity: an up to 18- to 20-year follow-up in an undergraduate clinic.

Purpose: This study investigated the possible relationship between the survival of complete crowns (CCs), 3-unit fixed dental prostheses (3uFDPs), and fixed dental prostheses (FDPs) versus gender and age at initial treatment over a period of 18 to 20 years in an undergraduate clinic.

Materials And Methods: Complete treatment and follow-up records of 1,037 CCs (60.5% women/39.

Survival of complete crowns and periodontal health: 18-year retrospective study.

Purpose: This study investigated the survival of complete crowns in relation to periodontal variables on a long-term basis.

Materials And Methods: A total of 1,037 complete crowns made in an undergraduate clinic for 456 patients were evaluated over an 18-year period. The study population was a mixture of periodontally affected and non-periodontally affected patients, which is comparable to the population group in a private practice.

Single-tooth replacement: is a 3-unit fixed partial denture still an option? A 20-year retrospective study.

Purpose: This study of 3-unit fixed partial dentures (FPDs) evaluated the long-term efficacy and determined the frequencies and causes of failures.

Materials And Methods: A total of 134 FPDs made in an undergraduate university clinic for 98 patients were evaluated over a 20-year period. All patients were offered a supportive maintenance program.

A 20-year retrospective survival study of fixed partial dentures.

Purpose: This study of fixed partial dentures (FPDs) evaluated the long-term efficacy and determined frequencies and causes of failures.

Materials And Methods: A total of 322 FPDs in 193 patients, fabricated at an undergraduate university clinic, were evaluated over a 20-year period. All patients were invited to participate in a supportive maintenance program.

An 18-year retrospective survival study of full crowns with or without posts.

Purpose: This study of full crowns investigated long-term survival in relationship to biologic and technical variables.

Materials And Methods: A total of 1,037 full crowns in 456 patients, made in an undergraduate university clinic, were evaluated over an 18-year period. All patients were offered a supportive maintenance program.
