Implant surgery

 
 

Implant procedures are becoming standard of many dental offices and must be offered by your dentist as alternative treatment to denture and traditional bridges.  Todays implant procedures are very successful if ideal cases are chosen.  Therefore, extensive screening is required prior to implant surgery.  These screening methods include: overall medical health evaluation, diagnostic radiographs, plaster models, periodontal screening, and CT-scan.  Perhaps, the most effective tool for implant decision making is the CT-Scan. A version of CT which is designed for the ora-facial use is called Cone Beam CT-Scan (CBCT).  The CBCT is specially designed for the head & neck application and will expose patients to considerably lower radiation  than the traditional CT-Scan.  The images generated from CBCT allow the dentist to view the jaws in three dimension so that accurate decisions can be made on the location, size , and angulation of the implant prior to the surgery.   Examples of CBCT are given below:


If you ever wonder what happens during implant procedures , you should also follow the link to our Dental Information page: Implant Dentistry .  In this section; however, we will explain what we do at Scident.  All stages of implant surgery and restoration are performed at Scident by Dr. Chehroudi.  We use primarily implants from ITI-Straumann , a Swiss-based company that we believe has superior biocompatible surface which allows rapid integration into the bone and soft tissue.  A recent paper by Dr. Chehroudi has shown the rapid bone formation with rough implant surfaces similar to that used in Straumann dental implant (B.Chehroudi et.al. Bone formation on rough, but not polished, subcutaneously implanted Ti surfaces is preceded by macrophage accumulation, Journal of Biomedical Materials Research, 2009).   Dr. Chehroudi has extensive research publications in the area of implant dentistry,and has many years of patient and laboratory experience in the field.


The surgical stage of the implant procedure starts with premedication of the patient with oral sedative and a select antibiotic to prevent potential biomaterial-related infection.  Although, the procedure is done under hospital-standard sterile environment, there is always a chance that oral bacteria attach to the implant surface prior to the tissue integration.  The operatory room, all surfaces will be decontaminated and covered by sterile drapes.  Operators and the surgical assistant also will be dressed in sterile gown.  The surgery will be guided by the data drawn from CBCT images so that precise and predictable placement of the dental implant is assured.  A surgical guide or appliance is often fabricated prior to the surgery which will guide the surgical drill in a predetermined pass. Often bone graft or cover membrane must be used to encourage bone formation and protect the implant from the oral bacteria.


The surgical area will be sutured so that the implant is covered under the gingiva (gum), and the patient will be dismissed to the waiting room where we monitor the recovery.  Because of oral sedative, usually a family member must accompany the patient home.


The post operative discomfort depends to the number of implant and the location.  However, it is often not more than what one may experience from the extraction of a wisdom tooth.  The bleeding should stop within a few hours on the same day, but potential swelling may persist for 2-3 days.   Please refer to the page on  “ Implant Post-Operative Care”  for details instruction after implant surgery.



Although, immediate loading of the implant in certain situations is possible; however, it may increase the chance of failure.  In Scident we prefer to start the restorative phase of implant procedure 2-3 month following the surgical placement.  This period allows the jaw bone to fuse and attache to the implant surface and secure it in place.  The restorative phase include exposure of the implant through the soft tissue (gum) for 3 weeks so that the gingiva around the implant matures.  A detail impression (mold) of the implant will be taken and send to the dental laboratory to fabricate the crown.  It usually takes 2-3 weeks to get the crown back, which will be cemented or secured with a miniature screw to the implant.


Implants can be used underneath dentures or partial denture to limit movement of the denture.  This procedure is particularly popular with the loose lower denture.  The procedure is called implant-supported over-denture and usually requires two implants and cost less than a free-standing implant with crowns.


Please ask our front staff to arrange a consult appointment so that we can evaluate your potential need for dental implants.  There is absolutely no need to suffer from a loose denture, or sacrifice your healthy teeth to replace missing teeth by a bridge.
