ClinConnect Summary
This clinical trial is studying two different types of dental implants for patients who need to replace a failed tooth in the front part of the upper jaw (maxilla). Specifically, it compares a new type of implant called the Co-Axis implant, which is placed at a slight angle, to a traditional conical implant. The goal is to see if there are any significant differences in outcomes between these two types of implants when they are placed immediately after removing a tooth.
To participate in this study, patients must be at least 18 years old and generally healthy, meaning they can safely undergo oral surgery. They should be able to maintain good oral hygiene and must have one tooth that is being removed due to poor health. It's important that there is enough healthy bone to support the new implant and that there are no ongoing infections. Participants will receive immediate implants and crowns, which means they will leave the appointment with a new tooth in place. If you're considering joining this trial, it's a great opportunity to receive cutting-edge treatment while contributing to important research in dental care.

Eligibility criteria
- Inclusion Criteria:
- • Patients who presented with a good well-being status and no contraindication for undergoing an oral surgical procedure
- • Patients aged 18 and over
- • Adequate oral hygiene, with patient's presenting a plaque index lower than 15% using the Index Scale publish by Löe et al.
- • Patients who demonstrated motivation and compiled by attending the allocated follow-up appointments
- • One single tooth indicated to be extracted due to having a poor prognosis in the maxilla (central or lateral incisors, canines or premolars)
- • Absence of vestibular dehiscence in the bone table and presence of soft tissue without recession (Alveolus type I according to the classification of Elian et al. which could be determined on the day of surgery
- • Sufficient bone to allow implant placement with primary stability
- • To avoid image blurring or artefacts during CBCT, patients were included if they did not have a bridge or amalgam restoration close to the implant placement.
- Exclusion Criteria:
- • If the patient presented with an acute infection in the tooth where the implant is to be placed
- • Absence of posterior sector in which it would cause an occlusal overload
- • Alveolus with enough space to place an implant with a diameter of 4.5mm (since implants with a 3.5 coronal diameter have a widening in the middle third of the implant of 4.5mm)
- • Patients with an unstable periodontal status
- • Patients who smoked more than 10 cigarettes a day
- • Patients who had medical histories which contraindicate implant surgery.
