Immediate dentures.

Conventional immeadiate dentures Interim Immeadiate/ Transitional

Conventional dentures. They are constructed as a permanent before extraction of teeth, where usually only anterior (and perhaps premolars) teeth remain. This denture can be relined, after healing of mucosa, for better adaptation and fit. This denture has good stability and retention. Cost is lower but treatment time is longer as interval of 3-4 weeks of healing of extraction sites must take place. General indications are few anterior teeth. Remaining anterior teeth would be extracted at placement, therefore 2 extraction visits are needed. Because posterior teeth have already been extracted, VDO may be lost. Esthetically cannot be improved.

Interim immeadiate dentures- constructed as temporary immediate until healing is complete and then a permanent denture has been made. Usually both anterior and posterior teeth remain. The stability and retention is fair/medium and must be improved by future relines. The cost is higher as 2 dentures are made but treatment time is shorter as denture is placed straightaway. Generally indicated when few posterior and anterior teeth remain and that already support wearing of a RPD that patient wants to retain. Because posterior teeth are remaining, the VDO is preserved and aesthetic can be improved in 2nd permanent prosthesis. At placement, all remaining teeth would be extracted, therefore 1 extraction visit is needed.

Working procedure of CID Extraction of posterior teeth and allowed to heal Impression taken in alginate Diagnostic cast made 2 layers of wax to block out undercuts in the dentulous areas of the cast Custom tray fabricated Occlusal rims fabricated over edentulous areas Posterior teeth seated and try in Anterior teeth broken away on the cast and trimmed up the cervical area and smoothened Teeth arrangement should be in harmony with existing natural teeth and artificial teeth Temporary denture base if flasked cured and polished Atraumatic extraction of remaining teeth to preserve bony contours and soft tissue
