How do endodontists feel about implants?
Endo:
In the majority of the studies, a successful outcome is strictly defined by complete absence of radiolucency and absence of clinical signs and symptoms. After nonsurgical treatment, complete normalcy has been named "success."
This definition is more strict than the definition for survival of implants.
A smaller radiolucency, in the presence of clinical normalcy, is usually considered as "incomplete healing."This combination is not considered as a successful outcome, but rather as an interim outcome requiring further observation.
In the case of necrosis + PA lesion: the success rate for RCT is around 94% if within 0-2 mm from apex...
RCT on a vital pulp has 95% success rate if gutta percha is within 0-2 mm from apex (Observation 4+ years).
The 5% failure can be retreated endodontically.
Compounded outcome of treatment + re-treatment has a success rate of 98%
If the retreatment fails you can do surgery
Thus, compounded outcomes of treatment + re-treatment + surgery would be 99% if within 0 - 2 mm from apex.
Holm-Pedersen, Lang, Müller. Clin. Oral Impl. Res 18 (suppl 3):15, 2007:
The survival of oral implants after 10 years varies between 82 and 94%.
Conclusion: Oral
implants, when evaluated after 10 years of service
do not surpass the longevity of even compromised but successfully treated natural teeth.

Additionally, animal studies show that researchers have been able to form roots and establish PDL between the newly formed roots and alveolar bone.
Limitation: availability of stem cells around the open apex of immature roots.
Enamel and dentin have also been produced under the skin of animals.
