ABSTRACT
When problems occur in multirooted teeth, such as persistent endodontic problems following endodontic treatment, problems involving fracture or furcation, extraction may be decided on. However, removal of the tooth will result in loss of occlusal units and the alveolar process. By removing the compromised root and preserving the healthy part, the tooth can remain functional, but only after restorative treatment. A correct indication or diagnosis, a properly performed endodontic, restorative and surgical treatment and proper follow-up are mandatory for a successful treatment outcome.

In a study, the effectivity and durability of telescopic dentures on abutment teeth provided with telescope crowns were investigated. The prognosis for the prosthetic structure and for the abutment teeth were both investigated. The survival rate of 234 telescopic dentures (886 abutment teeth) in 147 patients in a general dental practice were retrospectively evaluated on the basis of a status study. The mean survival rate was calculated. This is the moment when 50% of the telescopic dentures had failed. For telescopic dentures in the maxilla, this was 22.3±2.8 years, which did not represent a statistically significant difference from the mandible (20.9±1.9 years). Of the 886 abutment teeth that were used, 127 (14.3%) were extracted after an average period of 11.7 years. Periodontal complications were the primary reason for extraction. Based on this investigation, one could conclude that telescopic dentures are also a durable and sustainable solution in the long term. Loss of abutment teeth is relatively rare and has limited influence on the survival of the prosthetic structure.

Since the origin of tooth wear (attrition, abrasion and erosion) is multi-factorial, its diagnosis is complicated but vital. The so-called Tooth Wear Evaluation System, introduced earlier, makes a systematic diagnostic approach possible. The system consists of various modules, which can be used by the practitioner depending on the goal. Two new modules have been added to the Tooth Wear Evaluation System. The Therapy Start Module can be used to determine which one of the possible treatment modalities (counseling, monitoring, or restorative treatment) should be chosen. The Level of Difficulty Module gives the practitioner indications of the level of difficulty that may be encountered during a restorative treatment.

The restorative solutions for esthetic problems are becoming minimal invasive. Adhesive technology and materials as composite luting cements are biocompatible and therefor less harmfull for vital pulps. Necrosis of vital pulps hardly occurs and the survival of porcelain veneers is very good. The esthetic result is also quite impressive, although marginal discoloration is frequently reported. Full crown preparations can be avoided, but replacement of failing crowns is not banned out in dental practice. Full ceramic crowns however can also be luted with adhesive cements and the amount of hard tissue that has to be removed for optimal esthetic results is much less than for porcelain fused to metal crowns. Saving hard and soft tooth tissues is promoted and advocated as a quality standard. Longevity of treatment outcome has been reported and should be an evidence-based decision in the future.
