Full mouth rehabilitation of destroyed dentition with rotational path removable partial denture: a case report.

Kim MH, Heo SJ, Kim SK, Koak JY - J Adv Prosthodont (2010)

Bottom Line: According to the diagnosis, we determined to raise vertical dimension for esthetic and functional restoration.The final restoration was performed after four months of provisional period.The edentulous patients with compromised esthetics and functions can be successfully treated with a rotational path removable partial denture through adequate treatment planning and precise laboratory procedure.

ABSTRACT

Background: Though implant dentistry is very successful and predictable in treatment of patients with destroyed dentition, there are some cases with limitations to implant therapy. In these cases, alternative treatment modality should be considered.

Case description: A patient with destroyed dentition was rehabilitated with a lateral rotational path removable partial denture. According to the diagnosis, we determined to raise vertical dimension for esthetic and functional restoration. The final restoration was performed after four months of provisional period.

Clinical implication: The edentulous patients with compromised esthetics and functions can be successfully treated with a rotational path removable partial denture through adequate treatment planning and precise laboratory procedure.

Figure 6: Final prostheses; the stable occlusion was established.

Mentions: Final impression was made for PFG crowns. PFG crown copings were tried in the mouth to check for marginal fit. Before glazing, surveying was performed repeatedly for rotational path RPD. All PFG prostheses were cemented with resin modified glass ionomer cement (Fuji-cem, GC, Tokyo, Japan). To fabricate RPD framework, upper and lower master casts were made. Upper RPD was classified as Class III Mod. 1 RPD and was designed in lateral rotational path RPD with no clasp in the anterior region. Lateral or category II rotational path RPD in this report was surveyed in the next two steps (Fig. 4). The first surveying was performed at a zero-degree tilt to identify the mesial surface undercut of the anterior abutments (at least 0.010 inch) and buccal undercuts of the posterior abutments. The diagnostic cast was then tilled upward until the mesial undercuts on the anterior abutments were eliminated. The cast was again surveyed to determine if the anterior rest seats are accessible during the initial straight path of insertion. Lower RPD was conventional class I RPD with linguoplate major connector (Fig. 5). Both RPD frameworks were tried in the mouth and adapted with silicone material (Fit-checker, GC, Tokyo, Japan). RPD frameworks were very stable and showed very accurate fit and retention. For lower RPD, altered cast was made. A face-bow transfer was completed, and interocclusal registration was made with wax rim and bite material (O-bite, DMG, Hamburg, Germany). The casts were mounted in a semi-adjustable articulator. Denture teeth were set up to establish the stable and harmonious occlusion as such13: (1) Simultaneous bilateral contacts of opposing posterior teeth in the centric occlusion (CO) (2) unilateral balanced occlusion by denture teeth for left working side contacts (3) canine guidance by natural teeth for right working side contacts (4) contacts of opposing anterior teeth in the CO. After obtaining the patient's approval, RPDs were processed using pink denture resin (Rapidsimplified, Vertex, Zeist, Netherlands). The finished RPDs were placed in the mouth, and the following criteria were evaluated: adaptation of the clasps and rests, retention of the RPD, esthetics, and occlusion (Fig. 6). Finally the patient was instructed in placing the prosthesis and maintaining oral hygiene.
