• On the basis of above criteria the plaque status was “2” because plaque was observed with the naked eye and gingival status was given score 1 because mild inflammation was seen.
• No mobility of tooth was observed

• Canine to canine can be seen easily
• Part of mid-incisal area of lower mandibular teeth can be seen
• Patient gums are also seen which make it a gummy smile.
• Central incisors are prominent
![Page 19: Midline diastema dr arsalan](https://reader030.vdocuments.mx/reader030/viewer/2022020119/5873347e1a28ab596c8b741b/html5/thumbnails/19.jpg)
Clinical findings
• In maxillary arch ,spacing is seen in Maxillary central incisors
• Space is also present between central incisors and lateral incisors as well but this space is smaller than central incisors
• Space is also observed between lateral incisors and canine as well, which is very large and cannot be closed by restoration. Orthodontic intervention is mandatory for closing this space.

• Right central Incisor is labially placed to the arch form
• Spacing is also observed in the right canine and premolar as well
• Palate is shallow• Maxillary arch is large.• No spacing is observed in Mandibular arch.

Etiology of my case
Tooth and Arch Size Discrepancy because all the teeth are of normal size and spacing is also
observed generally.

Measurements and Investigation
• Length and width of right central incisors = 9mm• Length and width of right central incisors = 9mm• Length and width of right central incisors = 7mm

Midline space
• Space between central incisors are seen which was measured and found to be 1.5mm

Midline shift
• Midline shift was also observed which was about 1.5mm away from the mid line

Prediction of the fate of midline diastema
• It claimed to have an accuracy of 88%Sanin’s prediction is as follows:
Space between mixed dentition Possibility of space closure
1mm 99%
1.5mm 85%
1.85mm 50%
2.7mm 1% ( Treatment either ortho or restorative approach is mandatory)

Classifying Diastema according to treatment Plan
Diastema Size Treatment
Mild 1mm or less Direct composite( with enamel shade only)
Moderate More than 1mm but less than 2.5 mm
Direct composite restoration ( with enamel along with dentine shade is used)
Severe size More than 2.5 mm Direct veneering + orthodontic movement

Treatment Plan of my Case
• According to the above table, my case falls in moderate category of midline diastema. So the final treatment plan will be direct composite restoration ( enamel + dentine shade are used)
![Page 39: Midline diastema dr arsalan](https://reader030.vdocuments.mx/reader030/viewer/2022020119/5873347e1a28ab596c8b741b/html5/thumbnails/39.jpg)
Final treatment plan was done according to severity
Midline Diastema can be closed by direct composite restoration.
1. First the Diagnostic wax-up is made in order to judge the favourable outcome. So wax is added to the distal surface of right and left central incisor.
2. In the First step, the composite shade selection is done which is A2 Enamel and Dentine.
3. No preparation is done.

4. Adequate isolation is needed so rubber dam is placed, quadrant isolation is done from 1st premolar to 1st premolar of both the arches
5. Then the basic steps of restorations is followed
6. Then rubber dam is removed
7. Then finishing of the composite is done

• Both the incisors get more prominent due to increase in size
• Shade selection was not that adequate• Normal squarish shape of both the incisors is
not followed
