Molar incisor hypomineralization: supplementary, restorative, orthodontic, and esthetic long-term treatment.

Quintessence Int 2019 ;50(5):412-417

Objective: This article describes the esthetic results in a paradigmatic case of hypomineralized enamel correction on both anterior and posterior teeth to establish a minimal intervention protocol for similar cases. Clinical considerations: The subject was initially provided with casein-calcium-phosphate mineral supplementation. Unpublished laboratory images collected as part of a previously published study depict the results of initial calcium-phosphate supplementation on molar incisor hypomineralization (MIH) molar enamel morphology and indicate that this procedure is mandatory in moderate/severe cases.

Effectiveness of surface texture simulation of fixed dental prostheses by curvature analysis.

Quintessence Int 2019 ;50(5):378-386

Objective: The current design methods for the surface texture of prostheses are unsatisfactory: the line-drawing method relies heavily on the subjective experience of technicians, and the powder-coating method requires high costs. A new innovative method is proposed: curvature-analysis with reverse engineering. The objective was to compare operation times and esthetic parameters in generating surface textures among the three methods. Read More

Biomechanical behavior of maxillary premolars with conservative and traditional endodontic cavities.

Quintessence Int 2019 ;50(5):350-356

Objective: The objective was to evaluate the effects of the configuration of endodontic cavities with parallel or divergent walls, versus traditional endodontic cavities, on stress distribution, fracture resistance, and fracture mode of maxillary premolars by using both fracture-strength and finite element tests.

Biomimetic implant restoration made of human enamel and CAD/CAM block: a short report.

Quintessence Int 2019 ;50(4):330-333

This short report describes a clinical case in which an implant-supported crown was made using an extracted natural tooth as the outer shell. The same tooth had been previously relined for immediate loading without occlusal contacts. Using digital software, a composite resin mesostructure was fabricated in order to place the crown in the correct occlusal position, and the natural crown was ground using a computer-controlled milling machine to perfectly fit on the mesostructure.

Orthodontic extraction space closure with and without socket preservation: a comparative case analysis.

Quintessence Int 2019 ;50(4):306-314

Preorthodontic socket preservation after tooth extraction is intended to enhance favorable dentoalveolar ridge morphology and architecture, and facilitate orthodontic tooth movement (OTM) and extraction space closure. This 13-year-old skeletal Class II case presents a unique opportunity to evaluate and compare the OTM extraction space closure by means of a split-mouth analysis in a single patient. The comprehensive orthodontic-periodontal treatment included nonsimultaneous extraction of the bilateral periodontally compromised mandibular first molars and the eruption of bilateral impacted mandibular canines.

Noninvasive interdisciplinary treatment of a dischromic partially worn dentition.

Quintessence Int 2019 ;50(4):294-304

According to the classic concepts of prosthodontics the treatment of a patient presenting severely worn and dischromic dentition would involve a complex and demolitive treatment including periodontal surgery, endodontic therapy, posts and cores, and crowns; nowadays these problems can be solved with noninvasive procedures that allow preservation of dental and periodontal tissues. This article describes the interdisciplinary team approach (orthodontist, dental technician, prosthodontist) for the treatment of a patient showing attrition of the mandibular incisors in a deep bite relationship, contraction of the posterior sextants of both arches, diastemas in the anterior region of the maxilla, and highly dischromic teeth. The gingival tissue levels and the tooth malposition were corrected by orthodontic therapy, the abraded and the healthy dischromic teeth were restored with 20 additional veneers (the molars were the only teeth not involved in the restorative phase); tooth structure, tooth vitality, and bone level were maintained.

All-on-four rehabilitation using photogrammetric impression technique.

Quintessence Int 2019 ;50(4):288-293

Conventional implant impression techniques may introduce distortions in the framework that can lead to a lack of accuracy of the prostheses. Misfit between the restoration and the implants facilitates the occurrence of biomechanical failures and prostheses complications due to inadequate stress dissipation. Digital impressions present an alternative to eliminate procedural distortions by improving the fit between the restoration and the implants. Read More

In many areas of restorative dentistry, metal-free materials offer an alternative to metal-based restorations while ensuring high levels of biocompatibility and esthetics. Rapidly evolving CAD/CAM technology has significantly expanded the range of materials available, providing access to materials classes and their combinations not previously available within conventional manufacturing, such as zirconia ceramics and hybrid ceramics. In addition, digital methods offer previously unavailable options in diagnostics, greater planning reliability, better material quality through standardization of the manufacturing process, and reproducibility - significant benefits that can be used to advantage, especially in oral implantology.

Treatment of a maxillary second premolar with an associated cystic lesion through conventional endodontic therapy combined with decompression and cyst enucleation is reported. Although cystic lesions frequently heal simply with endodontic therapy, refractory large lesions after nonsurgical endodontic treatment may require additional diagnosis and treatment. In this case, conventional root canal treatment resulted in incomplete healing and required further surgery. Read More

Background: Bulimia nervosa is an eating disorder resulting in an intended weight loss due to decreased food intake, induced vomiting, or hyperactivity, and is observed frequently between 12 and 25 years of age. One of the complications is early tooth loss. Moreover, since bulimia nervosa patients suffer from increased atrophy of the alveolar processes, oral rehabilitation even with short dental implants may be impossible. Read More

Matthias Kern

Quintessence Int 2018 ;49(10):789-798

This article describes single-retainer resin-bonded fixed dental prostheses (RBFDPs) as an excellent alternative to orthodontic space closure or tooth replacement with implants or conventional fixed dental prostheses for congenitally and traumatically missing anterior teeth. Although the treatment with RBFDPs is technique sensitive, it is extremely reliable given a correct indication and adequate adhesive procedures. Read More
