LASER Sintered One-Piece Early-Loaded Dental Implants for Mandibular Premolars Replacement
This study was designed to evaluate laser-sintered early-loaded 1-piece implants (OPI) based on clinical and radiographic findings. Thirty OPI were placed in the mandibular premolar area and subjected to early loading after 3 weeks of initial placement; patients were followed up for 6 months. Clinical evaluation included pocket depth, gingival health, implant stability, and esthetics. Periapical radiographs were used to measure the marginal bone loss (MBL). All implants were considered successful resulting in a survival rate of 100%. A remarkable difference (P < 0.01) existed when comparing MBL levels at 1 month with those at 3 and 6 months. Significant differences (P < 0.01) existed when comparing implant stability at 1 month to 3 months and at 3 months to 6 months. Moreover, significant differences (P < 0.01) were observed when comparing peri-implant probing depth at 1 month to that at 3 and 6 months on both the mesial and distal sides. The mean value of pink esthetic score was 11 at time of final restoration. The laser-treated early-loaded OPI design is associated with satisfactory clinical and radiographic follow-up results and it is a good alternative to the 2-piece design.
Series of photographs and radiographs for laser-sintered 1-piece implant placement for a patient with missing lower first premolar due to extraction: Series A shows preoperative panoramic radiograph. Series B shows preoperative cast with the surgical guide in place. Series C shows prepared osteotomy site. Series D shows implant in place. Series E shows immediate postoperative radiograph. Series F, G, and H periapical radiographs show levels of marginal bone loss around the implant after 1 month, 3 months, and 6 months, respectively.
Series of photographs and radiographs for laser-sintered 1-piece implant placement for a patient with bilateral congenitally missing second mandibular premolar. Series A shows a preoperative periapical radiograph; in Series B, a photograph shows bilateral congenitally missing second mandibular premolar. Series C shows implant placement, and Series D shows implant in place. Series E shows an immediate periapical radiograph with the implant in place after initial placement. In Series F, a photograph shows final prosthetic restoration in place and in occlusion, 3 weeks after initial implant placement. Series G, H, and I, periapical radiographs show levels of marginal bone loss around the implant after one month, 3 and 6 months, respectively.
