Survey and Design

The successful use of a cast partial denture for a patient requires careful understanding of principles, forces acting on a partial denture,distribution of stress and design considerations.Equally important for all the designs are the length of edentulous span, quality of support of ridge, clasp design, denture base consideration and indirect retention.Swing lock partial denture would satisfy most of the requirement for the periodontally compromised dentition or patients with few remaining teeth.The use of surveyor would help the dentist to achieve optimum retentive undercuts, remove the interferences from maxilla and mandible,help to determine esthetic placement of clasps, determine the proper path of insertion and removal of prosthesis.The use of the removable partial denture for the patient with maxillofacial deformities is a challenge. Biological, physiological and psychological requirement have to be well satisfied for the treatment to be a success.It is critical to have a thorough knowledge of various factors on treatment planning and hazards inherent to prosthetic intervention.
