Silicone putty template records position of anterior teeth and is then retained = reproduction of anterior teeth site prior to processing
When try in is approved and template made = plaster teeth are cut from the model - level with the gingival margins
In the region of the removed teeth - residual undercuts removed and sharp edges sandpapered smooth
Modified models duplicated and clear acrylic surgeon’s guides are prepared and processed
Teeth extracted
Surgeons guides are placed over extraction sockets
Where blanching of the underlying tissues occurs, bone is removed
Insert dentures, correct occlusion defects
