ProsthodonticsIn a complete denture patient, which of the following is likely to cause difficulty in apposing the lips: failure to provide adequate interocclusal distance.

ProsthodonticsTitanium alloys are commonly used in dental implants due to their favorable properties, including biocompatibility and mechanical strength. The density of titanium alloys is relatively close to that of human alveolar bone, which helps in achieving a good integration (osseointegration) between the implant and the bone. Other materials listed, such as chromium-cobalt and stainless steel alloys, have different densities and are not as compatible with bone in terms of density and biological response. Bioglass, while biocompatible, is not typically used as a structural implant material in the same way as titanium.

Prosthodonticsguiding planes are flat, polished surfaces on the abutment teeth that guide the RPD along a specific path during insertion and removal. They are located adjacent to the edentulous area and are crucial for the proper seating and function of the denture.

ProsthodonticsArticulators are classified into arbitrary positional and functional by Boucher.
Arbitrary positional articulators hold the mandible in a pre-determined, fixed position that does not necessarily represent the patient's true centric relation or functional movements.
Functional articulators, on the other hand, aim to simulate the patient's individual centric relation and dynamic movements of the mandible, allowing for a more accurate representation of the patient's actual occlusion. Boucher's classification system is based on the type of articulation and the way it records and transfers the patient's jaw movements to the dental casts.

Prosthodontics
Explanation:In cases where there is a premature contact in centric occlusion, it is often necessary to adjust the opposing fossa or marginal ridge to achieve a more harmonious occlusion. This adjustment helps to eliminate the premature contact and allows for proper occlusal function.
