Implant too close to adjacent tooth?

Last Updated: Oct 24, 2012

I recently installed implants in #29, 28 edentulous sites [mandibular right second and first premolars; 45, 44].  I am concerned that the implant in #28 site may be too close to  #27 [mandibular right canine; 43] and that this might result in devitalizing #22.  Should I do prophylactic endodontic treatment on #22 or should I just continue to observe signs and symptoms?  Do you think the success of #28 osseointegrating will be compromised?  What do you recommend I do?

Ideally, 1.5 mm should exist between an implant and an adjacent tooth and 3 mm between adjacent implants. This spacing requirement is more important at the coronal end because it affects the gingival attachment to the adjacent tooth. It appears you have sufficient space at the coronal end between implant and tooth and if the implant is properly loaded and you dont get too much bone loss interproximally between #27 and implant, the gingival attachment to #27 should remain stable. Although the implant position does look close to the apex of #27, I do not think that prophylactic endo therapy is needed. I recently restored a case where the implant was in a nearly identical proximity to the adjacent tooth apex and the patient has had no symptoms of devitalization. Monitor and treat in future if necessary.

I'm sure you will not have any problem and a prophylactic endodontic treatment is not justified for now. osseointegration certainly will not be compromised. keep an eye on the patient as always

The real problem is ½ adjacent tooth bone atrophy (at least), which weakens the favorable prosthetic treatment and prognosis.

The position and the angulation of implants is good. Fot the relation with canine I thing it is safe but I note in your x ray there is alot of bone resoption distal to the canine I wonder is there any tooth mobility and to what grad. may be it is strong and that is nice but if it is mobile we need to chenge the treatment plan by extraction and implant in the area of canine.

I had a similar case- implant was too close to the root of UL3, worried, but the tooth survived. Regular check up with monitoring the vitality is all it needs,now. All the best.

I do agree completely with Salim. The implant is perfectly placed. only the tip of the implant is closed to the apex of the canine, and still you have 1.5 mm.distance to the apex of the canine, so you are just fine. I wish all my first mistakes placing implants where like this one you presented. Different situation of the problem would have been if the entire body of the implant were less than 1.5mm to the long axis of the tooth but no problem at all in your case.

You can always use fixed orthodontics to move the root of the canine slighly mesial. Use the implants as anchorage and the issue will be totally resolved. But first monitor, and proceed if needed. Have several like these with no problems.

Hello DOn't do endo right now. Wait and watch and do it later on if required. But i don't think you will need to do it. Best of luck sir.......

Test the tooth. It is unlikely that you have devitalized the tooth. You have to image your pilot drills in every case. This is an easy case, made.......... Bvinci

the placement of implant is quite good,as says Salim,if periodontal environment is safe, no worry at all,but if it is not, periomplantitis can occur and provoc a pulp necrosis by retro periapical infection
