(OPI) Oval Platform Dental Implants, are a new generation of dental implants. These implants have a wider implant structure (3.75 to 12 mm) and wider platform (oval Versus round platform) in comparison to the conventional dental implants which has been used in dentistry for a long period of time, with a common cylindrical tapered shape and round platform. OPI has also ticker body (3.75 to 6 mm) in comparison to the blade shape implants, (which had 2-3 mm thickness), which had a limited applications in dentistry before and due to breakage and high failure rate it is not being used in todays dentistry. Due to block shape of the OPIs structure (body), which bonds to the bone of the jaw, OPI provides better anchorage and support for supra- structure elements (Abutments) which connects to the implant by two screws (versus one screw in conventional implant) and supports a prosthetic part which could be fix or removable prosthesis (crowns and dentures). In OPI same material composition as conventional implant will be used, which has been used in dental implants for several years with the high rate of success in bonding to the jaw bone and having enough hardness to withstand the biting forces. These material can be Titanium Alloys and Hydroxyl Apatite.Linvention concerne des implants dentaires à plate-forme ovale (OPI), qui constituent une nouvelle génération dimplants dentaires. Ces implants ont une structure dimplant plus large (3,75 à 12 mm) et une plate-forme plus large (plate-forme ovale contre plate-forme ronde) par comparaison avec les implants dentaires classiques qui sont utilisés en dentisterie depuis longtemps, ayant une forme effilée cylindrique commune et une plate-forme ronde. Limplant OPI a également un corps plus épais (3,75 à 6 mm) par comparaison avec les implants en forme de lame (qui avaient une épaisseur de 2-3 mm), qui avaient auparavant des applications limitées en dentisterie, et, en raison dune rupture et dun taux élevé déchec, il nest pas utilisé a
