Placement and success of an implant depends upon various factors like medical ailments, parafunctional habits, compliance to oral hygiene, lifestyle choices (being a smoker/non-smoker), etc. Since the molar region receives the maximum bite force when a person bites, the implants in such cases requires additional care and planning prior to its placement . Not just the placement, but the final prosthetic rehabilitation plays a key role in the successful outcome of the treatment.
Next Steps
You should visit a good implantologist to get a full workup done and get a full mouth x-ray (OPG) and/or a CBCT scan done. It will aid in planning and determining the outcomes in a much better way
