Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Implant stability plays a major role in establishing implant osseointegration; it is considered an important requirement to decide the functional loading time with a fixed prosthesis. Objectives: to investigate the influence of one-piece implant position on their primary and secondary stability. The implant gains its Primary stability at placement time as a mechanical phenomenon that is related to the type of implant, placement technique used, and the local bone quality and quantity whereas, secondary stability is attributable to bone formation at the implant/tissue interface and in the surrounding bone. This study compares the stability of a compressive Conometric implant designed by Trade Company (ROOTT compressive with Conometric) in the posterior upper and lower jaws and optimizes the time of functional loading. This study's hypothesis is that implant stability is unaffected by the implant's position within the mouth cavity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Although Implant stability plays a major role in establishing the implant osseointegration, it is considered an important requirement to decide the functional loading time with a fixed prosthesis. Controlled loading is beneficial to maintain the implant stability during the early stage of healing as determined by resonance frequency analysis (RFA) measurement. There are different methods to determine implant stability, clinically examining the mobility by manual instrument, insertion torque value (ITV), electronic instrument, and radiograph evaluation of the bone around the implant; researchers found these are not sensitive enough. The introduction of quantitative methods, including the use of an RFA device (Osstell ISO, Integration Diagnostics AB, Gothenburg, Sweden) to measure implant stability, can yield valuable information, and its value range100. In contrast, a value greater than 70 is considered to indicate higher implant stability. Damping Capacity Analysis (DCA) device (Periotest; Medizintectechnik Gulden, Modautal, Germany) is another noninvasive method introduced to measure implant stability. Recently, Anycheck ( Neobiotech Seoul, Korea) is a modified DCA device introduced to measure implant stability, and Its value ranges from 1 to 99. Implant stability values of 1-59 were considered low stability; values of 60-64 indicated moderate stability; and values above 65 indicated high stability. The implant gains its Primary stability at placement time as a mechanical phenomenon that is related to the type of implant, placement technique used, and the local bone quality and quantity whereas, secondary stability is attributable to bone formation at the implant/tissue interface and in the surrounding bone. evaluated two-implant system stability using Periotest four months after the implant placement showed a mean of -1.9 for system A and mean of -2.1 system B whereas, Negative readings denote higher stiffness and a higher degree of osseointegration which indicated that implants were well osseointegrated and stable. Searching literature shows that applying different approaches to immediate loading can lead to survival rates in controlled studies comparable with those of conventionally loaded implants- however, this study is based on a small number. The selection of implant retained prosthesis type is a challenge for the dentist. Commonly there are different types of prosthesis retained to fixtures such as removable with precision attachment to the fixture and fixed restoration retained to the fixture either with cement or screw. Both cement and screw-retained fixtures have advantages and disadvantages like loos screw from time to time and remnant of cement under the restoration that leads to ridge mucous trauma. Conometric is another method to achieve retention of the prosthesis to the implant abutment, in addition to conventional cement and screw-based methods. Conometric works on the principle of frictional contact and elastic deformation of the connecting coping. Morse taper Conometric system used as implant-supported fixed dental prostheses retention found that the taper Conometric system can provide a retentive performance between implants and dental prostheses if proper insertion force is applied compared with cemented type without compromising the mechanical functionality of the system. Introduction One-piece implants with compressive threads, by ROOTT Implant Company, can be used for multiple units' restoration with immediate loading when adequate bone tissue is available. Studying the stability of a one-piece and comparing it to a two-piece implant suggested that both implant systems are clinically successful for dental rehabilitation and give consistent, longstanding results. Recently, this compressive implant was introduced with Conometric titanium caps (TEC) of different sizes and lengths. This study was conducted to compare the stability of a compressive Conometric implant designed by Trade Company (ROOTT compressive with Conometric) in the posterior upper and lower jaws and optimize the time of functional loading. This study's hypothesis is that implant stability is unaffected by the implant's position within the mouth cavity.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

One-piece implant

Preoperative CBCT for the implant area will be taken for analysis of anatomical features for all patients. Elastomeric impression will be obtained of both maxillary and mandibular arches, laboratory stone study casts will be made, and acrylic with metal sleeve surgical guide will be fabricated to localize the implant insertion position in the jaw bone without flap.

After the administration of infiltration local anesthesia, the surgical guide will be fixed in its position on the jaw arch, and a drilling sequence will be applied according to the manufacturer's instructions to create a hole for implant placement. The compressive one-piece implant (fixture and abutment) from ROOTT Trade Company will be inserted with appropriate neck and abutment length. The implant insertion torque will be adjusted to 35 Ncm by the wrench.
