Research objective This study will evaluate the clinical efficacy of Nobel parallel with on1 abutment compared to traditional healing cap in posterior teeth in a short term(one year) and long trem (five year) follow-up. 3. Study design and methods: Design type: prospective clinical study. Study duration: 5 years Start time: From the date of adoption of ethics. End time: 2026. Follow up examination: Panoramic images will be taken at all times to measure the marginal bone level of the implant.
