#1
Andreja Kuliš, Igor Kopač
Patients with an Angle Class III malocclusion are generally treated by orthodontics with or without orthognathic surgery. A literature search revealed very few articles describing solely the prosthodontic treatment of a Class III malocclusion, as it is rarely used as a treatment modality in these cases. The purpose of this article is to show the effects and benefits of an increase in the vertical dimension of the occlusion (VDO) in patients with a Class III malocclusion. An increase in the VDO causes a clockwise rotation of the mandible, thereby increasing the reverse overjet...

PURPOSE: The aim of this study was to determine whether dentists are able to discern and identify increases in occlusal vertical dimension (OVD) in dentate subjects without apparent loss of OVD. MATERIALS AND METHODS: A total of 10 dentate subjects had mandibular overlays fabricated at 2-, 3-, 4-, and 5-mm openings of the anterior guide pin (AGP) of a semiadjustable articulator. Standardized frontal and profile photographs with subjects wearing each of the overlays were made...

OBJECTIVES: Full-arch rehabilitations in young patients suffering from dental agenesis should compensate for the reduced vertical dimension of occlusion and restore both esthetics and function at minimal biological cost. This requires precise planning and maximum patient compliance during the preprosthetic phase. The pretreatment period with tooth-colored splints promotes a predictable outcome of the final restorations. Clinical considerations: Thanks to better restorative materials and adhesive techniques and increased knowledge of how to preserve sound tooth structures, prosthetic dentistry has increasingly turned toward minimally invasive procedures...

Worn dentition, often accompanied by occlusion changes such as reduced vertical dimension, poses a big challenge to both diagnosis and treatment. Current established causes fail to explain the observed tooth wearing patterns, and the treatments based on the documented pathogeneses are often unpredictable and require frequent maintenance. From the perspective of stomatognathic system, we postulate that the role of maxillo-mandibular relation is a crucial part in the tooth wear progression patterns, and should be well addressed in treatment planning...

Sebastian Hahnel, Christian Scherl, Martin Rosentritt
Polyetheretherketone (PEEK) is a polymeric material that has recently been introduced in dentistry and can be used as framework material for fixed and removable dental prostheses. This clinical report describes the fabrication of a double-crown-retained prosthesis with a PEEK framework in a patient with a substantially diminished occlusal vertical dimension. The insertion of the removable dental prosthesis with a PEEK framework resulted in the functional and esthetic rehabilitation of the patient; however, removable dental prostheses fabricated from PEEK should currently be regarded as interim restorations because of the limited available scientific evidence...

The comprehensive dental rehabilitation of complex prosthetic cases is often associated with increasing occlusal vertical dimension and transferring horizontal mandibular position in centric relation. The newly defined position of the mandibula should be functionally and esthetically evaluated for a longer time period before irreversible measures are performed. This case report discusses in detail a time-saving and economic direct method for increasing occlusal vertical dimension with long-term provisional composite restorations using a simplified injection molding technique and illustrates the complete intraoral and laboratory workflow...

PATIENT: A 60-year-old man presented for refabrication of his maxillary complete denture. In this case, a digital process was chosen to replace the ill-fitted complete maxillary denture. A specialized scan retractor was used to retract the mobile tissues of the lips, cheeks and vestibule while taking a digital impression. The interocclusal record obtained in the patient's mouth was scanned in order to digitally register the occlusal vertical dimension. The denture base and teeth were designed on virtual models that were mounted at the occlusal vertical dimension, and were made using CAD/CAM technology...

Determination of the occlusal vertical dimension (OVD) is an integral part of complete dentures fabrication. Due to the lack of teeth, the clinician faces the challenge of how to accurately establish the OVD of the new denture. Therefore, the purpose of this review article was to present, discuss and critique the available methods used in determining the OVD for complete dentures patients. This review identified two main streams to determine the OVD: (i) pre-extraction methods and (ii) post-extraction methods...

Shilpa Hiremath, Abhishek Jairaj
The purpose of this report is to introduce Cu-sil like denture as a functional space maintainer. Here, we report two paediatric cases treated with Cu-sil like denture with multiple edentulous spaces and partially erupted/compromised permanent teeth. Cu-sil like denture not only serves as removable partial functional space maintainer, but also restores the vertical dimension of occlusion, mastication and aesthetics in children. Cu-sil like denture is used in elderly patients who are not willing for extraction of remaining few healthy teeth in the oral cavity...
