This is what I do if I close this hole matching the surrounded topology by using Zmodeler.
- Edge-Bridge, 2.Edge-Insert, 3.Point-Stitch, 4.Point-Transpose.
Are there any better way to make it ?
The problem with manually rebuilding the topology polygon by polygon in this scenario is that you wont be able to exactly match the original curvature of the mesh.
Luckily, in this specific case (assuming spherical mesh from screenshot) it seems like it would be easy to simply Mirror and Weld (Tool > Geometry> Modify topology> Mirror and Weld ) the unbroken surface from one side to the other.
You will have to determine the correct axis to mirror along. M&W only works in one direction, so it may be necessary to flip the unbroken half to the other side first with Tool > Deformation > Mirror in order to mirror the correct side. If the sphere is not centered in your tool, you will also have to enable Local Symmetry (Transform > L.sym).

Thank you for your reply. Yes, that way is so effective for the symmetrical shape. Thank you.
On the other hand, If it is not the symmetrical shape, my way is the easiest way ? or Are there easier way ?
Your way is probably the easiest for that situation, though imprecise because it requires you to “eyeball” the curvature of the surface. If done at low enough poly, nobody else other than you is likely to notice anything. But if you want a pristine, unbroken curve on the surface, it would be better to plan your work in such a way that it doesn’t require you to manually reconstruct it.
If you have to, though, the alternate mode of the Move brush might be useful. The normal function of the Move Brush slides points around the screen viewing plane. If you first make contact with the point you want to move THEN hold down ALT, it will move the point along its normals instead, out from the center of the sphere. This will be useful when you have inserted the points in the correct place in the sphere’s topology, but only need to pull them out to match the curvature of the surface.
There are other alternatives that open up if you keep a duplicate copy of the unbroken mesh in place as a subtool before deleting those polygons. If the original and the altered subtool share the same space and the same topology, you’ll be able to cut pieces away from the original and weld them to the duplicate without moving anything into place. Or you can re-mesh the two back together with Dynamesh–though this will alter your topology.
Thank you so much. I could make my brain clear thanks to you.
