Plain English summary of protocol
Background and study aims
Dental implants are used to support false teeth. This is done to replace a root of a tooth by using a screw that connects the tooth into the jawbone. Dental implants can usually last a long time, however depending on the technique that the dentist uses could impact how long they can survive. Dental implants with a locking connection (such as Morse taper connection implants) can be placed in the mouth using two different grafting techniques. The aim of this study is to investigate the long-term survival and complication rates of dental implants placed using the Morse taper connection technique, in order to evaluate the predictability of this treatment procedure.
Who can participate?
Patients who underwent tooth implants from January 2003 to August 2006
What does the study involve?
Participants who underwent dental implants have their medical records reviewed in order to see what the ten year survival and complications rates are. Researchers gather data the implant survival, functioning, complications, infections and other clinically important events over ten years in order to evaluate the predictability of the treatment.
What are the possible benefits and risks of participating?
There are no benefits or risks with participating
Where is the study run from?
1. Dental Surgery Mangano (Studio Odontoiatrico Mangano)
2. Dental Surgery Frezzato (Studio Dentistico Frezzato)
When is the study starting and how long is it expected to run for?
October 2013 to May 2017
Who is funding the study?
Dental Surgery Mangano (Studio Odontoiatrico Mangano) (Italy)

| Scientific title | Morse Taper Connection Implants placed in Grafted Sinuses of 65 patients: a retrospective clinical study with 10 years of follow-up |
| Study acronym | MTCIsGS |
| Study objectives | The aim of this study is to investigate the 10-year survival and complication rates of Morse taper connection implants (MTCIs) placed in grafted sinuses. |
| Ethics approval(s) | Ethics Committee of the Hospital of Varese (Comitato Etico Ospedale di Circolo e Fondazione Macchi), 03/10/2013, ref: 826 |
| Health condition(s) or problem(s) studied | Implant dentistry |
| Intervention | This is a retrospective chart review study. The focus of the data collected is about the ten year implant survival and complication rates of a particular implant-abutment connection, the Morse taper. These records included all information about each enrolled patient (patient-related information: systemic health, age at surgery, gender, smoking habit, oral hygiene), each implant-supported restoration placed (implant-related information: position – premolar or molar – length and diameter; restoration-related information: type of prosthesis – SC or FPD - date of deliveries). The customized records included all information about any implant failure and/or biological/prosthetic complication occurred during the 10-year follow-up. The data collected from the medical record includes clinical functioning (implant survival and implant-supported restorations) and biologic and prosthetic complications. Implants were classified as “surviving” when still clinically in function at the final 10-year follow-up. Conversely, all implants that were lost and/or had to be removed (for implant mobility due to absence and/or loss of osseointegration in absence of infection, for recurrent/persistent peri-implantitis and for implant body fracture) during the entire period of the study, were considered as “failed”. Implant-supported restorations were classified as “surviving” when still clinically in function at the final 10-year follow-up. Conversely, all implant-supported restorations that had to be removed (for implant failure) during the entire period of the study, were considered as “failed”. Among the biologic complications, loss of the graft, sinus infection, peri-implant mucositis and peri-implantitis were considered. Among the prosthetic complications, all mechanical complications (i.e., complications affecting the pre-fabricated implant components at the implant-abutment interface such as abutment loosening and abutment fracture) and all technical complications (i.e., complications affecting the superstructures made by the dental technician, such as loss of retention, ceramic chipping/fracture, fracture of the metallic framework of restoration) were considered. |
| Intervention type | Other |
| Primary outcome measure(s) |
The 10-year implant survival (still clinically functioning) are measured clinically at the 10-year follow-up |
| Key secondary outcome measure(s) |
Biologic and prosthetic complications affecting the fixed implant-supported restorations are measured clinically during the ten year follow up |
