The study was performed in compliance with the Declaration of Helsinki. Data collection was performed in such a manner that subjects could not be identified, and therefore, it was exempt from IRB review according to Federal Regulation 45 CFR 46.101(b).

The current retrospective consecutive case series study provides preliminary data that treatment with 7-mm-length short implants with a hydrophilic electrowetted surface is a reasonable approach in sites with limited vertical bone dimension. It adds to the body of evidence supporting short implant use for compromised sites. The success seen might be attributed to the larger implant diameters that ...
Thirty-six percent of the implants in the study were placed in extraction sockets. Provided that sufficient initial implant stability is achieved, there should be no additional risk factors compared to implants in healed sites. Studies have shown no difference in marginal bone remodeling between immediately placed and delayed implants [15].
The biggest limitation of the current study is its very ...
A wide distribution in implant insertion torque (10–50 Ncm) was seen in the study. This reflects the variety of clinical situations in which the implants were placed. Assessments were made by using both the RFA value and the insertion torque as to first whether an implant should have been left to heal in the first place and if so, how this would be best accomplished, i.e., through its submergen...
This retrospective study is the first to look at short dental implants with a hydrophilic electrowetted surface. The survival data suggest that this treatment is a viable option to care. In a systematic review that identified 13 studies on implants shorter than 10 mm, the CSR from the individual studies ranged from 80 to 100% with a combined CSR of 98.3% after 5 years, 94.8% after 6 years, and ...
The chart review identified 86 placed implants in 75 patients. Table 1 summarizes the patient demographics of the 75 patients. Patients ranged in age from 29 to 88 years with a mean of 61.0 ± 12.5 years. Twenty-seven of the patients were males and 48 were females. Table 2 summarizes the implant and site-related information of the 86 placed implants. Mean insertion torque was 30.1 ± 7...
Baseline parameters, both patient- and implant-related, as well as follow-up parameters (implant survival, follow-up time, and resonance frequency analysis) were collected from a review of the patient records.
The main study parameters (principal outcome parameters) were defined to be implant loss and follow-up time. The cumulative survival rate was estimated. The influence of several factors on ...
A retrospective study on short 7 mm hydrophilic implants from a single center was conducted in a private practice limited to periodontics and surgical dental implant placements from one of the authors, PSR (Yardley, Pennsylvania, USA). An exhaustive chart review identified 75 patients for analysis that were treated with 86 short (7 mm) implants during a 5-year period (September 1, 2009, to Novem...
The aim of this retrospective consecutive case series study was to investigate implant survival rate and analyze possible factors affecting the survival of short implants placed in one surgical practice focused on implantology and periodontology in a temporal cohort.
In the past decades, the osseointegration rate of dental implants has dramatically increased, particularly in sites of softer dental bone, which may be attributed to the introduction of moderately roughened surfaces [1, 2]. Moreover, because of this increase in success, clinicians have attempted to push the envelope and place implants into sites that may provide a greater challenge as they wish to...
This retrospective consecutive case series study was performed to determinate the survival rate and implant stability of short (7 mm length) dental implants with an electrowetted hydrophilic surface that were in function from 1 to 7 years.
