Abstract

The purpose of this study was to analyze the color distribution of the maxillary primary central and lateral incisors using a dental spectrophotometer. Color measurements of maxillary primary central and lateral incisors of 32 pediatric patients aged 2 to 6 years were performed using SpectroShade Handy Dental Type 713000 (Serial No. HDL2678, MHT, Verona, Italy) by one researcher in the same clinic. CIE L*, a*, b* values of total surfaces and cervical, middle, incisal region were recorded. L* values were higher and a* values were lower in the primary central incisors than those in primary lateral incisors, but b* values didn’t show statistical difference. L* values of the middle region were the highest, and a* and b* values decreased from the cervical region to the incisal region. There were significant color differences between each region, and ΔE* ab between each region were greater than ΔE* ab between the primary central and lateral incisors. For esthetic restorations of primary incisors, it is necessary to consider the color differences between each region rather than those between the primary central and lateral incisors.

Abstract

Objectives: Management of a horizontal root fracture of an anterior teeth is challenging and often requires multiple approaches for improving the functional and esthetic outcomes. This case report describes the treatment and 2-yr follow up of 3 maxillary incisors with horizontal root fracture. Two maxillary central incisors were treated with Mineral Trioxide Aggregate (ProRoot MTA, Dentsply, Tulsa, OK, USA). Left maxillary lateral incisors were treated with endodontic treatment and submerged. During 2-yr of follow-up evaluation, the root-fractured teeth of the present patients were well retained in the arch, showing periodontal healing even after endodontic treatment.

Abstract

The osseointegrated implants react biomechanically in a different pattern to occlusal force, due to lack of the periodontal ligament unlike the natural teeth. The implants show markedly less movement and limited tactile sensitivity compared with the natural teeth. The implant occlusion concept aims to avoid overloading on the implants and to direct occlusal loads along the longitudinal axis of the implants, in order to compensate for the different biomechanics of the implants. Although many guidelines and theories on implant occlusion have been proposed, few have provided strong supportive evidence. Moreover, the outcome of treatment often quite successful in spite of different concepts of occlusion and there is an increasing tendency to doubt about the strict theoretical implant-specific occlusion concept. The purpose of this article is to review the previous reports about the concept of implant occlusion and discuss clinical occlusal considerations in implant rehabilitations.

Abstract

With the fourth industrial revolution, digitization is accelerating in all healthcare areas. In the field of dentist- ry, active discussions on digital dental technologies are ongoing, with increasing interest from clinicians daily. Thus far, accuracy and efficiency have primarily been emphasized in digital dentistry, and interest in occlusion has been relatively low. This is because digital dentistry has been predominantly used to restore small numbers of teeth rather than extensive prosthetic reconstruction. However, in the future, most dental treatments will undergo a digital transformation that will require the application of digital technology to more extensive prosthetic rehabilitation, for which discussion of occlusion is essential. In extensive prosthetic reconstruction, occlusion and articulation involve determining the position of the dental arch in relation to the reference plane of the skull or the long axis of the face and the position of the transverse horizontal axis. It also includes determining an occlusal surface with a shape that allows the mandible to move in an eccentric path and masticate most efficiently without any occlusal interference. To better understand how digitization will impact dentistry, this review ar- ticle summarizes and discusses occlusion and articulation using digital dental technologies. This discussion is divided into several aspects, including facial scan, virtual articulation, augmented reality, and virtual reality.

Abstract

Occasionally, complete dentures constructed in accord with the best clinical and laboratory procedures fail to serve successfully. These failures probably result from present ignorance of the occlusion and functions of living tissues. Nonetheless, in each case, the whole treatment procedure, both clinical and laboratory, must be reexamined in order to ascertain the point of failure. One can employ a technique more intelligently, and often improve on it, if the reasons for its use are known. When one is guided only by a recipe, the outcome will be doubtful whenever conditions are not the same as in the recipe. In this manuscript, occlusal consideration of edentulous patients will be discussed thoroughly.
