Dental implant risk factors
PEARL Network risk factors JADA 2014 July
- History severe periodontitis
- Preexisting inflammation in site (endo lesion or perio lesion)
- Type IV bone
- Immediate vs delayed
- Anterior vs posterior
Risk Factors (highlight those linked to “cluster phenomenon”)
- poor bone quality or bone bone support
- untreated chronic periodontitis
- active infections
- systemic diseases (diabetes = 5-10% decrease success rate but not sure if that is untreated? Lit review says no difference Cheng 2015 JADA July)
- smoking (heavy=seen 10-15 called heavy) 2x failure rate 4x in augmented bone
- unresolved caries or infection
- advanced age
- short and/or small implants
- eccentric occlusal loading
- inadequate number implants
- parafunctional habits
- bisphosphonate discontinue oral 3 months before surgery if >3 years
- hx radiation treatment (8 years post radiation is even worse not sure why?)
- SSRI Wu 2014 J Dent Res
- Antidepressants (doesn’t breakdown into types) Chrcanovic 2016 J Dent Res

Dental Implant Risk Factors
Reasons for dental implant failure
Risk factors include – untreated periodontal disease, systemic disease, smoking, unresolved caries or infection, advanced age, short/small implants, inadequate number of supporting implants, parafuncitonal habits
Options Remove implant, debride site, clean CHX and/or NaCl .9% Baxter Health, graft
Cluster failure – is when multiple implants fail on the same individual risk factors of this condition are lack of bone support or quality, heavy smoker, short implants, existing periodontitis and bruxism
Dental implant bone loss risk factors
What are the patient risk factors for bone loss around dental implants from Ting 2017 Implant Dentistry systemic review?
- Periodontal disease is a major risk factor, with aggressive periodontitis being worse than chronic.
- Less bone loss in grafted sockets but more in ridge augmentation sites.
- More bone loss in smokers and in men.
- Smokers have more in the maxilla than the mandible.
