What you are looking at are casts and diagnostic photos of a patient that started with the practice several years ago. In the photo above, the 2nd PM is actually #4.
Here's a little history...
The patient presented with extensive caries and fractured teeth.  RCT #s 4 & 5 necessary and post placement.  The crowns were in occlusion and functional approximately 3 years.  Tooth # 12 has a floating pontic.  Teeth #'s 8, 9 & 10 are veneered, #s 10 & 11 are crowns.  She has had several fractured teeth which required extraction.  
Every 3 months she is seen by a periodontist.
Teeth #'s 4 & 5 fractured at the alveolar crest and were extracted.  Implants have been placed.  She states her mother also fractured her PMs.  
I hesitate to restore her implants with the occlusal issues.  Where to begin?
My observations are these-
1.  She appears to have immediate disclusion on protrusion- interference noted in the posterior.
2.  Deep bite with lingual and facial wear.
3.  No stable posterior occlusion.
4.  Repeated fracturing of teeth.
5.  Left side- all the crowns have fractured porcelain.
6.  No pain.
Questions:
1. Here envelope of function seems violated- is that right and where do I even begin on this one?
2.  Do I temporize the implants and place her in a splint?
3.  Do I place her in partials and expect to temporize the anterior teeth to work out occlusion?
4.  Do I punt this one to a prosthodontist?
5.  What do I tell the patient as to why this occurred?
