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.
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.

Patient selection were selected according to selected criteria.
dental implants were applied as recommended by the manufacturer.
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.

RFA measurement
two SmartPeg transducers were used on each implant, and three measurements were completed: therefore, total number of registers was six for each implant. All assessment was carried out consecutively regardless register time or location. Measurements were completed by one only experienced dentist with knowl- edge of the Osstell ISQ system for RFA assessment
Time frame: the 1st (T1), 4th (T4), and 12th (T12) weeks
Periotest measurement
The periotest device is placed in a horizontal position 0.6-2 mm away from the tooth surface and two PTVs (PTV1 and PTV2) were calculated with a time difference of 20 min. During each measurement, the device delivers 16 impacts in 4 s to the object.
Time frame: the 1st (T1), 4th (T4), and 12th (T12) weeks
Pocket probing depth
Measurement of the depth of a sulcus or periodontal pocket determined by measuring distance from a gingival margin to the base of the sulcus or pocket with a calibrated periodontal probe.
Time frame: he 1st (T1), 4th (T4), and 12th (T12) weeks
