Extraction of #31 and 32 and Implant Placement at #30 and 31

The tooth #30 has been missing for a 49-year-old lady (ZY) for several years with mesial tilt and shift of the teeth #31 and 32 (Fig.1).  A large crown was fabricated at #29 to close the edentulous area.  The poor restoration creates traumatic occlusion to the tooth with bone loss (Fig.1 *).  With removal of the restoration and scaling & root planing, the bone loss appears to be resolved at #29 in 2.5 years (Fig.2).  Three months post implant placement at #2, the patient will return for extraction of #31 and 32 and implant placement at #30 (possible Tatum) and 31 (UF in the distal socket, treated with Metronidazole) (Fig.3 green lines).  Initial osteotomy depth will be 10 and 8 mm.  PA(s) will be taken to confirm the depth.  It is estimated that 5 and 6 mm implants will be placed at #30 and 31, respectively (Fig.4 red outlines).  Tap drills have to be used prior to implantation.

If the tooth #32 is too mobile, keep it and trim the mesial surface for space for #31 implant crown.

Pre-implant exam shows that #31 is salvageable.
