Implant Anchorage for Orthodontics
A 58-year-old man (JQ) has poor dentition. After implant at #20, he wants more at the lower right sextant (Fig.1). Since the tooth #29 tilts distally (Fig.7,8), which affects #30 implant placement, implants will be placed at #28 and 31 first. After extraction (Fig.2), the sockets will be treated with Metronidazole.
Because the socket at #28 is oblique, the initial penetration for osteotomy should address the issue, to be placed in the mesiolingual slope (Fig.3 red line)). Once the entry point is established, the osteotomy should be redirected and parallel to the long axis of the normal tooth (Fig.4 white line). Appropriate implants are placed (Fig.5 green outlines). The implant at #31 should be placed as mesial as possible relative to the extraction socket (Fig.7,9). When the implants osteo-integrate, brackets or bands (Fig.6 white boxes) are placed on the provisional crowns (pink) and #27, 29 for segmental orthodontics. Place Class V composite at #29 before bracketing (Fig.9 *).
After the angulation of the tooth #29 is corrected, an implant is going to be placed at #30.
Five months post #28 and 31 placement, lower ortho starts.
