BONE REHABILITATION OF INCISORS

PERIODONTAL TREATMENT PRIOR TO PROSTHESIS

REALIGNMENT OF INCISORS

COMPLETE REHABILITATION OF HALF AN ARCH

OBIETTIVI
  • Treatment of bone defects of the upper arch. Construction of a fixed prosthesis for the lower teeth and a prosthesis with attachments for upper ones.
  • To treat bone defects prior to application of a prosthesis.
OBJECTIVE
To treat bone defects prior to application of a prosthesis.
Fig. 1 Case at beginning. A chamfered mucoperiosteal flap will be sculpted on the inside to eliminate the periodontal pocket and gain access to the bone defects; then, following curettage and scaling in the mesial bone defect at 1.7, osteoplastics will be performed with an osteotribe.
Fig. 3 A piece of Interpore 200 is prepared by modelling with a Beaver 64. Fig. 4 Interpore 200 implant in the bone defect.
Fig. 2 Easily visible bone defect in three parts (which does not involve the trifurcation) following curettage and bone remodelling.
Fig. 5 Bone implant seen mesially at 2.2 for the correction of a crater that cannot be treated only with resective surgery and mesially at 2.1 for treatment of a hemiseptum.
Fig. 6 After modelling the implants on the palatal side as well, suturing is performed with single stitches. After six months a cast gold core will be created in 1.7.
Fig. 7 Avulsion is performed on 3.4 because of the severe periodontal damage. Fig. 8 Excision for the new attachment in the lower arch
Fig. 9 A temporary prosthesis in 3.3-3.5 is created, maintaining crossbite
Figs. 10-11 Prosthesic preparation of upper teeth to realign them, correct crossbite and stabilize them definitively with a temporary prosthesis with palladium alloy bite to maintain the vertical dimension.
Figg. 12-13-14 The procedure is repeated for the lower arch

OBJECTIVE
To construct a fixed prosthesis for the lower teeth and one with attachments for the upper teeth

Fig. 15 A palladium alloy prosthesis, with rough modelling with resin as a test piece, is constructed to check and record the necessary occlusal and gnathological data. Fig. 16 The centricity, laterality and protrusive waxes are recorded
