Dental implants when your mouth is too small?

Please consider having another dentist evaluate the area and offer a second opinion.  There are risks with any option you choose.  The risk for a partial denture is that it can act as a slow tooth extractor.  By teetering on the abutment teeth over and over, a partial can cause damage to the health of supporting teeth.  If the oral surgeon can place the implant, most likely there is a dentist that can properly restore the implant.  Talk to you oral surgeon about what your dentist told you and perhaps ask their office staff who they would go to if they needed to have an implant restored.  Go there for a second opinion.  At least you will have more information to make an informed choice.  Usually either option is better than doing nothing which could lead to teeth shifting and problems with the way your teeth come together in biting.

if mouth opening is not enough to accommodate implants drills, in that
case little angulated implant is advisable but in that case more chances
of failure just because of improper force distribution.
