ABSTRACT
Introduction: Osseointegration as formulated by Alberktson is crucial for implant survival and success. Osseointegration is a measure of implant stability. Measuring implant stability helps to arrive at decisions as to loading of an implant, allows protocol choice on a patient to patient basis and provides enhanced case documentation. The RFA technique provides with clinically relevant information about the state of the implant–bone interface at any stage after implant placement. Aim: Evaluation of primary and secondary stability between implants of two different systems by resonance frequency analysis device. Methodology: This study was conducted among 17 patients divided into two groups. Group 1 (n = 10) receiving 20 MIS seven implants and Group 2 (n = 7) received 20 Alphadent active implants. The primary implant stability was measured at the time of implant placement and secondary stability is measured at 3–4 months interval using RFA device OSSTELL ISQ. Statistical analysis was performed using paired t test for intra group and independent sample test for intergroup comparisons. Results: No statistically significant differences in primary and secondary stabilities were found between the implant systems at either time intervals (P > 0.05). A positive correlation was noticed between mesiodistal stability and implant diameter in MIS seven group (P < 0.05). A positive correlation was noticed between mesiodistal, labiolingual stabilities and implant diameter in Alphadent group (P = 0.03). A positive correlation was noticed between mesiodistal, labiolingual stabilities and implant length in Alphadent group (P = 0.03). Conclusion: From the present data, it can be concluded that within the limitations of study, implant systems used and their design features showed no significant correlation to implant stability between the groups. More studies are required to assess the effect of implant designs and surface conditions on implant stability on a long-term basis.
ABSTRACT
A manera de cavilación se pretende hacer un llamado a la investigación y a la mesura que abra un espacio para el trabajo en equipo en el que se hace imprescindible la planeación y en donde el nivel de evidencia basado en estudios con diseños metodológicos adecuados hacen creíble y traducible la información que se ofrece sobre esta temática que sin duda es actual y polémica. Además de tratar en concreto lo que la evidencia muestra sobre las uniones diente-implante y que aun se considera un tópico controvertible, se profundiza en la limitación de estudios con buenos diseños metodológicos que permitan llegar a conclusiones importantes en esta área biomédica. Igualmente, el considerable desconocimiento en la mayoría de protocolos de carga inmediata y temprana con implantes orales vistos en diferentes situaciones de edentulismo no es contemplado por algunos programas de escuelas odontológicas y casas comerciales que los avalan y popularizan basándose en investigaciones muy lejanas a las adecuadas y con un buen nivel de evidencia
As a reflection this article intends to make a call for the research and for the restraint, while opening a space for teamwork in which planning is prevalent and where the level of evidence-based studies with adequate methodological designs make credible and translate the information on this subject that is current and certainly controversial. It deals specifically what the evidence shows about tooth-implant unions that are still considered a controversial topic, also, describes the limitation of studies with good methodological designs that will lead to important conclusions in this biomedical area. Similarly, considerable unawareness in most protocols for immediate and progressive implants loading in different edentulism situations is not pondered by some dental schools programs and commercial corporations that consider them very popular and based on research far from adequate with a good level of evidence

Recent development of dental implantology has taken an interest in the bone graft procedure. This is a review of literature, published from 1994 to November 1999. This study is provided by MEDLINE search. In this study, 718 patients received 829 graft with placing 2,677 endosseous implants. In mandible, nonvascularized or vascularized block bone grafts provided better results (success rate 95.2%) than particulate grafts(83.6%). But in maxilla, particulate grafts provided better results(93.7%, 86.2%) and more cases especially in sinus elevation. There were many cases using autogenous bone graft and revealed good results, but allogenic or alloplastic bone graft materials also were used by many surgeons.
