The patient lost her upper first molar and adjacent premolars on right hemisector 16, 14,15) . Noting that she still have her wisdom tooth(18) intacted. Which are the teeth to be in the future brigde as pillars?
God no. Extending the bridge doesn't make it better; it simply involves more teeth and more risk. Also makes it harder to align the drilling of the teeth so the cuts have to be deeper. Sometimes you just have to accept you can't do what you want.
Explore the option of partial denture. Most of my patients can't afford implants. In my opinion, bridges are too barbaric in drilling and permanently damaging so many teeth. Partial denture feels awkward and the hassle of taking in and out. But it provides for some function.
