Implant Survival to 36 Months as Related to Length and Diameter

Abstract

The results indicate that: 1) shorter implants had statistically lower survival rates as compared with longer implants; 2) 3+ mm diameter implants had a lower survival rate as compared with 4+ mm implants; 3) 3+ mm diameter implants are less stable (more positive PTVs) than 4+ mm implants; and 4) there was no significant difference in crestal bone loss for the two different implant diameters between placement and uncovering.

The survival of dental implants with different implant-abutment connection systems

“…The survival of the implants involves the following factors as well: the experience of the implantology center (multicenter study) [1,6], the dimensions of the implants (length, diameter) [19], the use of single or combined implants in the prosthetic phase [12], the place of implanting [6,7] and the habit of smoking [8,14]. At the same time, other publications have not demonstrated the effect of the above-mentioned and other factors on the survival of implants [4,5,7,9,13,18].…”

A New Implant Designed to Maximize Contact With Trabecular Bone: Survival to 18 Months

“…29 Several reports suggest that higher failure rates are associated with the use of short implants. 3,30,31 Microstrains, which are concentrated at the bone-implant interface, may result in microfractures that may result in eventual loss of the involved implant if not allowed to repair. Cortical bone is denser, stronger, and repairs at a slower rate compared with trabecular bone.…”

Various Treatment Options for the Single Implant in the Mandibular Anterior Region

“…Small diameter implants are often chosen for cases where there is a reduced availability of alveolar ridge width or interdental space. However, the reduced surface area for osseointegration [22,23] and the increased risk for implant fracture [24,25] in such cases may contradict the use of small diameter implants. However, mechanical tests have shown higher tensile and fatigue strength of zirconium compared to pure titanium.…”
