Improving Esthetics of Removable Partial Dentures Using Palatal Retentive Arms

Success and complication rates of non-precious alloy telescopic crowns in a general dental practice

OBJECTIVES

This retrospective, single-center, practice-based cohort study aimed to analyze factors associated with the success of removable partial dentures retained by telescopic crowns (TRPD).

MATERIALS AND METHODS

TRPD which were placed in a single practice of a practice-based research network were analyzed. Data from 139 patients (age (SD): 66 (11) years; 66 female) with 174 TRPD including 488 non-precious alloy telescopic crowns (TC) between 2004 and 2016 were included. TC without any technical complication were considered as successful, and as survived, if they were still in function at the last check-up. Multilevel Cox proportional hazard models were used to evaluate the association between clinical factors and time until failure.

RESULTS

Within a mean follow-up period (SD) of 4.2 (3.3) years (min-max: 1 day-12 years), 372 (76%) TC (AFR5years,TC-level: 5.0%) as well as 136 (87%) TRPD (AFR5years,TRPD-level: 5.1%) ("worst-case scenario") and 150 (86%) TRPD (AFR5years,TRPD-level: 3.4%) ("best-case scenario") were considered as successful. The main failure types were recementation (n = 39), endodontic treatment (n = 36), and extraction (n = 35). TC in male patients showed 1.6 times higher risk for failure than in female patients (95%CI: 1.1-2.4; p = 0.023). TC on premolars showed 2.2 times higher risk for failure than on incisors (95%CI: 1.1-5.0; p = 0.023) and TC in dentures with ≤ 3TC showed 2.1 times higher risk for failure than TC in dentures with > 3TC (1.3-3.4; p = 0.042). Furthermore, TC on the most distal tooth in an arch showed 2.4 times higher risk for failure than TC on a more mesial tooth (1.5-3.8; p < 0.001).

CONCLUSION

For removable partial dentures retained by telescopic crowns, high success rates could be found after up to 12 years. Patient-level and tooth-level factors were significantly associated with failure.

CLINICAL RELEVANCE

For removable partial dentures retained by telescopic crowns, high success rates could be found after up to 12 years. Patient-level and tooth-level factors were significantly associated with failure.

Prosthodontic Rehabilitation and Follow-Up Using Maxillary Complete Conventional Immediate Denture

Despite global efforts to improve individuals’ oral health, a considerable proportion of patients still progress to the stage in which the extractions of all teeth in one arch or both are indicated. An immediate complete denture remains a relatively accessible treatment option, particularly for those patients who cannot afford or do not need implant treatment. It is often one of the best solutions when the complete extraction of the remaining teeth is unavoidable. The denture is fitted immediately after the surgical clearance of teeth. It acts as a splint for helping with haemostasis, preventing trauma, and promoting wound healing. More importantly, an immediate denture can copy the characteristics of the existing dentition and establishes the vertical dimension of occlusion. It offers immediate replacement of the missing teeth, thereby avoiding a period of edentulism and social embarrassment. These treatments help relieve patient anxiety and bring about patient satisfaction. This study used a case report to illustrate the clinical procedures required for the construction of an immediate complete maxillary denture with good retention, support, stability, and aesthetics.
