A patient came in with a broken implant body remaining in the site of tooth #30 (Fig. 1). No information about this implant was available, because the dentist who had placed the implant had retired years ago and moved out-of-state.
In my office, the broken implant body was removed successfully (Fig. 3). 4 months later, a new implant was placed surgically on tooth #30. Then, another 4 months later, a new crown was fabricated and seated (Fig 4).
To remove the broken implant body, a small carbide bur #330 was used. Using the carbide bur, holes were drilled and connected to make a trench around the broken implant (Fig. 2). The implant was then tipped using a small surgical elevator #301 and removed with cotton pliers.
To minimize bone loss, a small carbide bur #330 was selected. A diamond bur was not selected to avoid dropping any loose diamond particles and embedding them in the tissue of the tooth #30 site. While drilling holes with a carbide bur #330, precise care was taken to avoid touching the broken implant body and prevent any ground metal particles from becoming embedded in the tissue.
When the crown was seated, the proximal contacts of the crown were adjusted prior to cementation by using the ContacEZ Black Diamond Strip. After cementation, trapped interproximal resin cement was removed with the White Serrated Strip. The ContacEZ Gray Final Polishing Strip was then used to polish the surface to restore a natural finish and confirm Interproximal Relief (IR). The complete marginal seating of the new implant supported crown is done.
