Digital vs Analog Impression in Cases of All-on-4 - Prosthesis

24. februar 2021 opdateret af: October University for Modern Sciences and Arts

In a Post -Covid-19 World, What is the Clinical Influence of Digital vs Analog Impression in Cases of All-on-4 - Prosthesis ?

Fifty six patients were randomly enrolled in the study. Participants were randomly stratified into two control groups and two test groups, from which conventional pick up and digital impressions were made respectively. Patients of group 1 (CIG Axial) and 3 (DIG Axial) received 4 axial implants whereas, group 2 patients (CIG Tilted), and group 4 (DIG Tilted) received two anterior axial implants and two distal tilted implants.

All participants received hybrid dentures. Bone loss, implant loss, maintenance of prosthesis were evaluated at 6m,12m, and 24 months follow up period.

Foranstaltningsbeskrivelse
Tidsramme
implant loss
Tidsramme: 24 months
The implants were considered surviving if they were clinically stable and functioning without any mobility. Failure was defined removal of implants due to loss of integration, pain, implant mobility, paraesthesia, neuropathies or psychological reasons. Calculation of the estimated failure rate was performed by dividing the number of implant failures by the total exposure time of the implant. The total exposure time is the interval of time the implants could be followed for the entire observation time or up to failure of the implants that were lost during the follow-up period.

Tidsramme
crestal bone loss
Tidsramme: 24 months
Standardized periapical radiographs with long cone paralleling technique using film holders were used for the assessment of crestal bone loss. The loss of marginal bone relative to the implant shoulder at the mesial and distal of each implant was measured in mm and then the mean was calculated and statistically estimated. A digital intraoral imaging system was used (Digora phosphor plate reader, Soredex Tuusula, Finland). All the radiographs were scanned and then uploaded into the computer for assessing bone loss over time. The "ImageJ" software was used to take the measurements on the computer screen. Postoperative radiographs with the implants placed at the crest of the bone were compared with the 6,12 and 24 m radiographs.

Tidsramme
maintenance
Tidsramme: 24 months
During the follow-up period, prosthodontic (mechanical) complications for the four groups were registered and calculated according to the following events: number of screw loosening or screw fracture of the abutment, number of screw loosening or screw fracture of the prosthesis, number of framework fracture, fractured acrylic resin, number of prosthetic teeth fracture and loss of cover of access hole.
