Alloplastic Implantation
HA is available in block form (porous or solid) and as granules. It is used most commonly to augment the contour of the facial skeleton or as a bone graft substitute in orthognathic surgery. Contouring of HA blocks is performed with dental burs.
Modification Procedures
Most PMMA scleral lenses are fenestrated to permit tear flow and oxygen exchange behind the lens. If a fenestration hole becomes covered by the upper lid regularly or is otherwise blocked as by loose conjunctival tissue or mucus, then a further hole (or holes) may be required within the palpebral aperture.
Electrical Injuries
Contact points on areas such as the scalp and torso add complexity to management. Scalp burns that spare the galea are managed by excision and grafting directly onto the galea. Wounds that penetrate or expose the outer table of the skull or deeper require a different approach.

The principles of tooth replacement
When examining the casts, movement of the RPD away from the cast is identified. Any denture will have a path of displacement away from the cast/mouth. It is possible to introduce a path of insertion and removal which is different from the path of displacement ( Fig. 12.30 ).
