About

Implant stability is critical to successful osseointegration, the direct structural connection between the dental implant surface and bone. Implant stability must therefore be measured to evaluate implant success. The study evaluated the osseointegration of different sizes with two devices measuring stability with different methods.

Full description

The 39 implants, 4.0 and 4.5 mm in diameter and 10 and 12 mm in length, in 19 patients were included. Hounsfield unit (HU) values obtained on cone beam computed tomography (CBCT) were recorded. Stabilities were measured with Periotest and resonance frequency analysis (RFA) at day 0 (intra-operative) and the 1st (T1), 4th (T4), and 12th (T12) weeks. Probing depth (PD) and bleeding on probing (BOP) scores were compared between T1 and T4.

Enrollment: 19 patients

Sex: All

Ages: 20 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• having partial tooth deficiency in the posterior region of the lower jaw (molar tooth deficiency)
• having an indication for dental implant-supported fixed prosthesis
• at least 6 months had elapsed since the last tooth extraction in the area to be implanted
• having a soft tissue thickness of at least 1.5 mm and adherent gingival width of at least 2 mm
• the existence of panoramic and dental volumetric tomography images of the area to be implanted
• the presence of a suitable recipient bone for implantation with dental implants of the desired length and diameter
• completion of periodontal treatment and provision of oral hygiene training; and acceptable existing gingival health and oral hygiene for implant application (periodontally healthy) in the oral examinations performed following periodontal treatment.

Exclusion criteria

• being in American Society of Anesthesiologists (ASA) Class 3 or 4 according to the ASA Physical Status Classification System

Patient selection

Other group

Description:

Patient selection criteria were as follows: absence of any systemic disease; not being in American Society of Anesthesiologists (ASA) Class 3 or 4 according to the ASA Physical Status Classification System (Doyle, 2017); being older than 20 years of age; the existence of panoramic and dental volumetric tomography images of the area to be implanted; the presence of a suitable recipient bone for implantation with dental implants of the desired length and diameter.

Treatment:

Other: Patients selection

Dental Implant Application

Other group

Description:

Bredent SKY® dental implants were applied at a torque level of 30 N.cm as recommended by the manufacturer. The surgery and all measurements were performed by the same surgeon.

Treatment:

Other: Implnat placement

Osseointegration and periodontal measurements

Other group

Description:

Following the operations, the stability of the dental implants was measured at the 1st (T1), 4th (T4), and 12th (T12) weeks using Periotest (Periotest M, Modautal/Germany) and Osstell (Osstell AB-W\&H, Sweden) devices. In accordance with the manufacturers' recommendations, the final implant stability quotient (ISQ) and Periotest values were determined by calculating the average of three measurements per implant. At the same time, periodontal index values of probing depth (PD-mm) and bleeding on probing (BOP-%) were recorded at the site of the dental implant at T4 and T12.

Treatment:

Other: Recall visits
