The junctional epithelium (JE) is an epithelial component that is directly attached to the tooth surface and has a protective function against periodontal diseases. In this study, we determined the origin of the JE using a bioengineered tooth technique. We transplanted the bioengineered tooth germ into the alveolar bone with an epithelial component that expressed green fluorescence protein. The...

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch and the talon cusp is a rare dental developmental anomaly seen on the lingual surface of anterior teeth. This paper presents a rare clinical case of development of talon cusp in a mesiodens with multiple lobes, which interfered with both occlusion and appearance of an 11-year-old patient. During clinical interview, t...

DESCRIPTION A healthy 18-year-old male patient came for a routine dental examination. His medical history was uneventful. Mandibular left central incisors exhibited small prominent cusp on its lingual surface (figure 1). The cusp was teatlike, projected from the cement–enamel junction and extended halfway to the incisal edge. The cusp measured 4.5 mm in length (incisocervically), 3.5 mm in widt...

Reference scanners are used in dental medicine to verify a lot of procedures. The main interest is to verify impression methods as they serve as a base for dental restorations. The current limitation of many reference scanners is the lack of accuracy scanning large objects like full dental arches, or the limited possibility to assess detailed tooth surfaces. A new reference scanner, based on fo...

Automatic occlusal surface reconstruction for all kinds of tooth restorations is an important ongoing research topic. It is undisputed that an automation of the restoration process is only possible if the typical geometry of teeth is known by the system. One realizable approach is the restoration of the occlusal surface by adapting an appropriate tooth model. A first prototype [7] that was deve...

An integrated single-tooth modeling scheme is proposed for the 3D dental model acquired by optical digitizers. The cores of the modeling scheme are fusion regions extraction, single tooth shape restoration, and single tooth separation. According to the "valley" shape-like characters of the fusion regions between two adjoining teeth, the regions of the 3D dental model are analyzed and classified...

Introduction: This study was designed to observe the success of three quarter crown over conventional full veneer crown in the posterior teeth (premolars and molars) where there has been considerable destruction of tooth structure but with the buccal surface remaining intact. Method: A total number of 30 patients were studied. Among which 15 patients were treated with three quarter crown and re...

BACKGROUND The aim of this study was to investigate the efficacy of orthodontic treatment using the Invisalign® system. Particularly, we analyzed the influence of auxiliaries (Attachment/Power Ridge) as well as the staging (movement per aligner) on treatment efficacy. METHODS We reviewed the tooth movements of 30 consecutive patients who required orthodontic treatment with Invisalign®. In all...
