The invention discloses a measuring device and method for the
implantation site in dental implantation. The measuring device comprises a ruler I, a ruler II, a ruler III, a ruler IV, a ruler V and a ruler VI, wherein the ruler I is used for gap measurement and diagnosis and
implant positioning when in loss of single
premolar tooth; the ruler II is used for gap measurement and diagnosis and implantpositioning when in loss of single
molar tooth; the ruler III is used for continuous
implant positioning when in loss of continuous teeth; the ruler IV is used for gap measurement and diagnosis and
implant positioning when in loss of continuous
premolar teeth; the ruler V is used for gap measurement and diagnosis and implant positioning when in loss of continuous
molar teeth; the ruler VI is usedfor gap measurement and diagnosis and implant positioning when in loss of continuous
posterior teeth. The measuring device and method disclosed by the invention have the beneficial effects that by adoption of the measuring device provided by the invention, auxiliary positioning can be carried out on the conventional oral-cavity implantation
surgery at the posterior-teeth area; the cost is low, the operation is simple, the use is convenient, the accuracy is high, the error is small, the ideal position of the implant can be more accurately and quickly positioned in the
surgery.
