Abstract

ABSTRACT Objectives Materials and Methods Results Conclusion Clinical Significance This study compares the restoration of single‐tooth implants with screw‐retained lithium‐disilicate hybrid‐abutment crowns and single‐tooth lithium‐disilicate crowns adhesively bonded to hybrid abutments with regard to objective clinical and subjective patient‐specific evaluation criteria over a time of observation of 3 years.Two bone‐level implants were placed in contralateral sides of the same jaw in 10 patients, each with two single‐tooth gaps. After osseointegration, implants were uncovered and an impression was taken. In accordance with the split‐mouth design, one implant in each patient was restored with a screw‐retained hybrid abutment crown and the other implant with a hybrid abutment and an adhesively bonded single‐tooth crown. The restorations were randomly allocated to the implants. Prefabricated titanium bases were used. The ceramic abutments and restorations were fabricated monolithically with pressed lithium‐disilicate ceramic. An objective evaluation (survival, technical, or biological complications, FIPS) by the practitioner and a subjective evaluation (satisfaction, OHIP) by the patient were carried out after 3, 6, 12, 24, and 36 months after restoration placement.Both restoration types showed a survival rate of 100% after 3 years of observation. No technical or biological complications occurred. No significant difference was observed between the two types of restoration neither for objective (survival, technical or biological complications, FIPS) nor subjective (satisfaction, OHIP) evaluation criteria (p > 0.05).No statistically significant differences were observed between screw‐retained and cemented pressed lithium‐disilicate restorations on bone‐level implants for both objective and subjective evaluation criteria, respectively.Monolithic hybrid‐abutment crowns (screw‐retained) and monolithic hybrid abutments with single‐tooth crowns (cemented) made of pressed lithium disilicate can be used to successfully restore single implants.

Abstract

The purpose of this clinical study was to assess the feasibility of forced orthodontic extrusion with the Tissue Master Concept to retain subgingivally fractured teeth as abutments for which extraction and replacement would be equal treatment opportunities. Participants were recruited from a group of consecutive patients in need of prosthodontic rehabilitation. In total, 36 deeply destroyed teeth in 31 patients underwent forced orthodontic extrusion with forces exceeding 50 g to reestablish biologic width and ensure a 2-mm dentin-ferrule design prior to single-crown restoration. The primary endpoint was the success of the extrusion in terms of the ability to restore the respective abutment tooth. Information about overall treatment time, frequency, and reasons for failure were collected. Four patients dropped out of the treatment. For the remaining 27 participants, data were fully collected. The amount of extrusion ranged between 2 and 6 mm (3.5 ± 0.9 mm), and the mean duration until retention was 20 ± 12 days. On average, patients returned three (± 3) times for control visits after extrusion. Adhesive failure (n = 6) and orthodontic relapse (n = 2) were the most frequent complication types. Forced orthodontic extrusion may be a useful tool to restore teeth evaluated as nonrestorable. [ABSTRACT FROM AUTHOR]
