I'm sure you will all find these paper interesting: Manfredini D, Poggio CE, Lobbezoo F. Is Bruxism a Risk Factor for Dental Implants? A Systematic Review of the Literature.Clin Implant Dent Relat Res. 2012 Nov 13. doi: 10.1111/cid.12015. [Epub ahead of print]

Sam thanks for your welcome! My feeling is that if there is still existing periodontal propioception (some remaining teeth, natural or restored) motor control is much more accurate than in completely edentulous patients with all implants. Of course if the clinical condition allows it I would be always happy to have eccentric contacts on teeth, however obviously periodontal as well as biomechanical conditions are usually much more relevant in deciding which teeth to maintain than occlusal considerations. A "hopeless" tooth is always a hopeless one, although if it has propioception. If however there are teeth that can be maintained with a reasonable prognosis and a reasonable treatment plan I would say that there are several advantages in keeping them.

the occlusion in implant dentistry is definately very complex ,whether in contact or no contact or no eccentric contact or occlusion has no role in implant dentistry,what to follow very nice presentation,i was asked questions on occlusion in my fellowship exam of AAID america ,examiners should go through this webinar

Carlo; Welcome to the Xpert family at XP and thanks for your literature review. Is it your feeling that natural teeth should support off axis forces or lateral excursions over implants when there remains natural teeth combined in the arch with dental implants? thanks Sam

Dear Nikos thank you, you are absolutely right! Propioception is a real problem in fully edentulous patients treated with implants, a careful distribution of guidance is absolutely necessary, moreover I really think that if it is possible (of course unfortunately it is not always possible) to preserve some occlusal contacts on teeth the pattern of movement is absolutely different. Of course this requires a careful evaluation of biomechanical as well as periodontal risk factors of remaining dentition (if still present). I do not have experience with T-Scan, though there is some literature questioning reproducibility and clinical usefulness of it. Thank you again!

Congratulation carlo for a Great presentation of the Implant Occlusion Dilemma.My 22 year experience with Implant prosthodontics has taught me that the Lack of proprioception is the main issue and the resulting lack of muscle inhibition . So i see necessary to have a very shallow guidance with a group function and use of a T Scan to have an objective registration of forces. Carlo what is your personal approach to these Design Criteria?

Wendy AuClair literature is important, then of course there is clinical practice...thanks for your comment!

Nice review of the literature - Looking forward to Part 2!
