Home / FAQ / Product NO section Characteristics of ORLUS 1 Question What is the difference of ORLUS compared to other mini-screw systems ? Answer The main disadvantage of mini-screw type orthodontic implant is the relatively low success rate. ORLUS orthodontic mini-implant have been developed to solve problems related to the stability. ORLUS orthodontic mini-implant has the unique design (the Patent No.0430770) to increase the success rate. 2 Question Is really the success rate of ORLUS is over 90%? Answer The unique design of ORLUS orthodontic mini-implant has been proved by clinical researches and 5 year clinical experiences. (research) ORLUS orthodontic mini-implant makes the stability technique-independent and site-independent. With recommended protocols for insertion, even the beginner can get the reliable stability(Direct approach / Indirect approach). 3 Question How long have ORLUS mini-implants clinically used? And, are ORLUS mini-implants clinically proved ? Answer The first prototype of ORLUS mini-implants was developed in 2001. More than 20,000 of ORLUS mini-implants have been used per year in Korea. And the effectiveness of ORLUS mini-implants has been proved by many clinical cases. 4 Question Can ORLUS be used in the growing patients? Answer The bone quality and quantity is relatively poor in individuals younger than 15 years of age, therefore, it is unfavorable for obtaining the primary stability. To increase the success rate in the growing patients, the surface of ORLUS is treated to increase the biocompatibility. And, with the protocols for younger patients, ORLUS is also useful in the growing patients. NO section Case selections of ORLUS 1 Question What type of treatment can be accomplished with mini-implants? Answer ORLUS mini-implants provide rigid anchorage, therefore, ORLUS can be used for all kinds of tooth movement within the biological limits; For example, anterior flaring, anterior retraction, anterior intrusion, anterior extrusion, posterior protraction, posterior distalization, posterior intrusion and much more. 2 Question What age of patient is the best for application of ORLUS mini-implant? Answer Patients with permanent dentitions is the most adequate for application of ORLUS mini-implant. For patients with mixed dentitions, areas in which a successor tooth bud exists should be avoided whenever possible. 3 Question When should not mini-implants be used? Answer When the general condition is compromised, precaution should be paid in the application of mini-implants. And when the quantity and quality of cortical bone is inadequate for obtaining primary stability, the success rate may be low; For example, the success rate may be low if it is placed where there is no opposing tooth or where a tooth was extracted recently. 4 Question How can I decide where I insert ORLUS mini-implant? Answer The quantity and quality of the host bone bed should be appropriate for the primary stability, and it is preferable that areas where the potential of irreversibly injuring important anatomical structures is high should be avoided whenever possible(Site selections). NO section Procedure of ORLUS 1 Question Does anesthesia have to be applied for insertion? Answer A local anesthesia is necessary for the surgical procedure. 2 Question Does a flap procedure have to be done before insertion? Answer No, it is not necessary to perform a flap prior to placement. But, for the placement on the frenum area, frenectomy is essential. 3 Question Is pre-drilling required to insert? Answer ORLUS mini-implants can be placed without pre-drilling. They can simply screw in with a hand screwdriver because of a cork-screw like tip and apical reverse buttress threads. But, pre-drilling through the cortical bone by a specially designed hand drill is recommended to eliminate the iatrogenic root injuries, to prevent the fracture of the implant tip, and to minimize surgical trauma. 4 Question Does anesthesia have to be applied for removal? Answer Mostly, no anesthesia is needed for removal. Very rarely, a local anesthesia may be needed for very sensitive patients. However, in the case that the implant head is covered with soft tissue or an implant is to be inserted deeply, infiltration anesthesia is needed. 5 Question Is special hygiene maintenance indispensable? Answer Normal hygiene maintenance is all that is required. 6 Question Can ORLUS mini-implant be loaded right after insertion? Answer Immediate loading is possible if the enough primary stability is obtained.
