Greetings!

In an effort to continuously update you and your staff on the latest trends in dentistry, I present to you the second issue of the Examiner Online.  Knowing what your periodontist can offer your practice could greatly help you in making treatment decisions that would give your patients the comfortable, functional and esthetic dentition they always deserve. I hope you find this publication helpful and please do not hesitate to contact me with any question.  Your input is greatly appreciated.
 
Thank you,

Single Tooth Implant in the Esthetic Zone

A single tooth restoration in the anterior maxilla is the most challenging restorative procedure in dentistry.  The challenge is significantly compounded when an implant serves as the prosthetic support. Although osseointegration is a very predictable event, placing and restoring an implant that meets the criteria of esthetic success is the most complex implant procedure for the surgeon and the restorative dentist. The trend of immediately placing implants in the anterior maxilla after extractions have proved successful.  Kemppainen et al. (1) reported a 99% success rate using one and two stage implants. Other studies have recommended one stage implants and immediate load with success in specific situations(2).  In my practice, I have been placing provisional restorations on implants at the time of insertion for several years.  Most of the implants that I placed following that protocol were in the lateral and central positions, however, implants in the upper and lower bicuspid regions were also successfully provisionalized at the time of surgery. Making and placing the immediate provisional restoration in my office allows me to properly control the soft tissue drape and ensure a successful final restoration.
Case Study
A 36 year old patient was referred to my office for the extraction of tooth #10 and replacement with a dental implant.  The tooth was deemed hopeless due to root fracture.  The clinical and radiographic evaluation revealed adequate bone width and height for the placement of a dental implant.  No evidence of an acute lesion was noted and the patient was considered a good candidate for an immediate implant and immediate loading with a provisional abutment and restoration. 
 
Tooth # 10 was extracted using bone preservation technique and a Biomet 3I Prevail 4/5/4 x 15 implant was placed.  A provisional abutment was placed at the time of the surgery and a provisional restoration was placed.  The provisional crown was out of occlusion and the patient was instructed to avoid biting on that area for eight weeks. The patient returned to the restorative dentist after three months for the final restoration.  The implant was restored with a zirconium abutment and a full porcelain crown.
