Using Resonance Frequency Analysis to Compare Delayed and Immediate Progressive Loading for Implants Placed in the Posterior Maxilla: A Pilot Study

Abstract

Objective:Implants placed in the posterior region of the maxilla have a high incidence of implant failure due to poor bone quality, especially when immediate implant loading is needed. Immediate Progressive Loading (IPL) can enhance bone quality and may offer an alternative solution when Immediate Implant loading is needed.Methods:Six patients (one male and five females; 34-62 years old) were included in this study. Twelve implants were inserted in the posterior region of the maxilla. Resonance Frequency Analysis (RFA) was performed at the time of implant placement and after 1, 2, 3 and 6 months. ISQ (Implant Stability Quotient) values were compared between the Delayed Loading (DL) group after 2 months and the Progressive Loading (PL) group and between different time points for each group.Results:At implant placement, the mean ISQ values for PL and DL implants were 63 and 57, respectively. One month after implant placement, the mean ISQ value for PL implants was 73.Two months after implant placement, the mean ISQ value for PL implants was 75. Three months after implant placement, the mean ISQ values for PL and DL implants were 76 and 69, respectively. Six months after implant placement, the mean ISQ values for PL and DL implants were 79 and 76, respectively.Conclusion:Despite its limitations, this pilot study indicated that compared to DL, PL can enhance bone density and implant stability, resulting in greater early functionality and fewer surgery sessions.

Resonance frequency analysis of implants placed in condensed bone

“…The immediate insertion of implants into fresh extraction sockets (Hämmerle et al, 2004) has become a common surgical protocol with considerable research interest. RFA is widely used to measure stability after immediate placement (Qabbani et al, 2017) and even immediate loading (Juboori et al, 2018). However, bone structure in fresh extraction sockets differs considerably from healed sockets or edentulous bone regions (Araújo & Lindhe, 2005;Cardaropoli et al, 2003).…”

“…This fact could be explained by the micro-threats in the part of the implant body, which achieved the lowest 52 units at the time of measurement. This fact is by the publication done by Al Juboori et al, [19] who assure that two months after implant placement, the mean ISQ value for implants was 75, and 79 after six months, respectively.…”

“…Progressive bone loading is a procedure in which it is prudent to abstain from exposing partially mineralized bones to substantial loads in a single instance. Allowing adequate time for the bones to mineralize and augment their density (Juboori et al, 2018), progressive loading is recommended for implants in poor bone‐quality sites, particularly in the posterior maxilla (Turner & Nentwig, 2014). Furthermore, it can reduce crestal bone loss compared with conventional loading for poor bone quality (Appleton et al, 2005).…”
