Objectives of pre-prosthetic surgery

Flangeless denture: an innovative technique for management of labial undercut in completely edentulous patient: a case report

“…7 Some authors have mentioned this as "wing denture" in which the labial flange is segmented in the labial frenum area and two wings show up from either side, which provides adequate space for the labial frenum. 8,9 Another conservative treatment option include use of soft liners that can easily adapt in the undercut area without causing trauma to underlying mucosa. 10…”

“…1 To eliminate the undesirable labial undercut of maxillary ridge, removal of the minimum amount of bone is necessary while avoiding the loss of bony cortical plate and thus it can improve the environment for the complete denture construction. 2 Pre-prosthetic surgery is one of the treatment option in such cases before advancing towards the construction of complete denture. Reconstructive preprosthetic surgery helps the prosthesis to reestablish work, guide maintenance, fulfill esthetics and save related remaining structures.…”

Preprosthetic Surgery

“…An understanding of patients' surgical and prosthetic expectations must be clear and a determination made as to whether these goals can be achieved. 1 Special emphasis is placed on systemic conditions that may directly affect bone healing.…”

“…When bone is adequate, procedures such as lingual balcony reductions, removal of redundant soft tissue, and skin graft vestibuloplasty may enhance stability. 1,2 Adequate occlusion requires a reasonable skeletal relationship between the jaws. For patients with severe skeletal class II or III relationships, orthognathic surgery may be indicated as a preprosthetic procedure.…”

Flangeless Denture: A Simple Yet Novel Approach for Management of Severe Labial Undercuts in Edentulous Patients

“…Removal of the minimum amount of bone necessary to eliminate the undercut, while at the same time avoiding the loss of bony cortical plate can be done for such conditions in order to improve the environment for denture construction. [4] Some patients do not give their consent for undergoing a surgery to correct the undercut while some are deferred from surgical procedures due to certain systemic conditions. In such patients a novel technique can be followed in order to fabricate a prosthesis which will be esthetically pleasing and acceptable for the patient.…”
