Abstract
Even though dental attachments have a long successful history, many of the dental practioners are unaware about its benefits in daily clinical practice. It highly improves the comfort, aesthetic, function and patient satisfaction, especially in the patients with long span edentulism where implants and fixed partial denture (FPD) are not indicated and cast partial dentures are barely satisfactory. This case report describes the clinical and the laboratory steps for prosthetic rehabilitation of a patient with maxillary distal extension partially edentulism with cast partial denture using Preci Vertex attachments.
Highlights
Precision and semi precision attachments are not a new invention in dentistry
In case of tooth-tissue supported prosthesis, resilient types are highly recommended to avoid torque to the abutment tooth
Factors that determine the choice of attachment depends upon types of prosthesis, location of the attachment, function, retention, space available and cost
Summary
Precision and semi precision attachments are not a new invention in dentistry. They have been in use in dentistry since early 20th century. Precision attachments: They are prefabricated, often milled from alloys and are very precise. They are soldered or welded to crown/coping or prosthesis. They are rigid.[3 2]. Semi-precision attachments: They are usually available in plastic forms and are cast, less precise. Intracoronal attachments: They are placed within the contour of the crown. They require a huge box preparation and often demand endodontic treatment. Most of them are key and key-way type and are rigid. e.g. Crismani attachments
